Abstract:
The polybutoxytitanates catalysis of aniline acylation by orthosubstituted benzoic acids leads to the production of substituted benzanilides. Catalytic rate constants of the second order reaction (the first with respect to aniline and ortho-substituted benzoic acid; boiling ortho=xylene, 145°C) correlate well according to the Hammett and Bronsted equations with straight line segments with ρ=1.93 and α=0.66, in contrast to the reaction of aniline with meta- and parasubstituted benzoic acids and substituted anilines with benzoic acid. This dependence drops out 2=nitrobenzoic and 1=naphthoic acids, which have relatively low reactivity and the greatest steric hindrances both for nucleophilic attack by aniline and for possible coordination with catalytically active centers of the corresponding ortho-substituted titanium polybutoxybenzoates formed in situ. Based on these data, the previously proposed mechanism of bifunctional catalysis due to titanium polybutoxybenzoates and their complexes with meta- and parasubstitutedbenzanilides was supplemented by the possibility of the steric inhibition of reaction by the most bulky substituents and chelate structures formation of orthosubstituted benzoic acids and their anilides with individual titanium atoms of the catalyst, as well as the simulta­neous H-bonding of the amino group hydrogen atoms of aniline, which leads to its activation to a nucleophilic attack, with a carbonyl group and an orthopositioned substituent of the orthobenzoate ligand in the coordination sphere of titanium. Taking into account such chelation and steric barriers, as well as inhibition of acid catalysis due to the formation of the imide form of anilides, containing electron-withdrawing substituents, the equations for the rate constants of the catalytic reaction of ortho-substituted benzoic acids with aniline are derived, corresponding to the experimentally obtained Hammett dependence.

Abstract:
The complex dielectric spectra of 2-butoxyethanol with aniline and substituted anilines like aniline, o-chloroaniline, m-chloroaniline, o-anisidine and m-anisidine binary mixtures in the composition of different volumes of percent (0%, 25%, 50%, 75%, and 100%) have been measured as a function of frequency between 10 MHz and 30 GHz at 298.15 K. The dielectric parameters like static dielectric constant ε0 and relaxation time τ have been obtained by using least square fit method. By using these parameters ε0,τ, effective Kirkwood correlation factor geff, corrective Kirkwood correlation factor gf, Bruggeman factor fB, excess dielectric constant εE, and excess inverse relaxation time 1/τE values are calculated and discussed to yield information on the dipolar alignment and molecular rotation of the binary liquid mixtures. From all the derived dielectric parameters, molecular interactions are interpreted through hydrogen bonding.

Abstract:
Nitrogen-containing carbon derivatives were prepared by the carbonization of poly(aniline-co-p-phenylenediamine) cryogels in inert atmosphere. Lower aniline fraction in the comonomer mixture used for preparation of the cryogels led to the decrease of their thermal stability, a consequent increase of carbonization degree, and less defective structure of carbonized materials. The resulting carbonaceous products had up to 4 orders of magnitude higher specific surface area than their respective cryogel precursors, the highest value 931 m2 g−1 being achieved for carbonized poly(p-phenylenediamine) cryogel. Electrochemical characterization of the carbon derivatives demonstrated that the decrease in aniline concentration during the synthesis of the precursor cryogels led to higher gravimetric capacitance for corresponding carbonized materials. These materials can potentially be used for energy storage applications.

Abstract:
Three simple compounds that have the potential as a hole transporting layer (HTL) based on pyrazine derivatives conjugated with electron donor groups in the form of triphenylamine have been successfully synthesized and characterized. The synthesis began with a substitution reaction at high temperatures between 4-bromoaniline and 4-iodoanisole to produce 4-bromo-N,N-bis(methoxyphenyl)-aniline, followed by substitution of bromo atoms with tributylstanum at low temperatures and inert atmosphere (N2) producing 4-methoxy-N-(4-(tributylstanyl)phenyl)aniline. The conjugation reaction was carried out through a Stille coupling reaction between 1,2-bis (4-bromophenyl)ethane-1,2-dione with 4-methoxy-N-(4-(tributylstanyl)phenyl) aniline at high temperatures with the aid of a Pd(PPh3)4 catalyst in an inert atmosphere (N2). The reaction was continued with the imination reaction with 3 compounds, i.e., 1,2-diaminobenzene, 3,3-diaminobenzidine and 2,3-diaminopiridin to produce three HTL compounds that were namely 4’,4”-(quinoxaline-2,3-diyl)bis (N,N-bis(4(methoxyphenyl)-[1,1’-biphenyl]-4-amine) (DNB), 4’,4’’’,4’’’’’,4’’’’’’’-([6,6’-biquinoxaline]-2,2’,3,3’-tetrayl) tetrakis(N,N-bis(4-methoxyphenyl)- [1,1’-biphenyl] -4-amine) (bDNB), and 4’,4’’’-(pyrido[2,3-b]pyrazine-2,3-diyl)bis(N,N-bis (4-methoxyphenyl)-[1,1’-biphenyl]-4-amine) (DNP). The optical and electrochemical properties of DNB, bDNB, and DNP were analyzed by UV-Vis and Differential Pulse Voltammetry (DPV). The optical and electrochemical properties show the energy levels of the HOMO and LUMO of the three compounds. Hence their potential can be estimated as HTL compounds. The three compounds show λmax of 348 nm, 356 nm, and 350 nm for DNB, bDNB, and DNP. Based on DPV results, the HOMO values for DNB, bDNB, and DNP are -5.03 eV, -5.02 eV, and -4.98 eV and LUMO values of -2.46 eV, -2.76 eV and -2.87 eV, respectively. The three compounds' thermal properties were analyzed using TGA, with the results showing that the three compounds had good thermal resistance with a decomposition point above 400°C. Based on optical, electrochemical, and thermal analysis, DNB and bDNB have almost the same properties. Thus, it is expected that the three compounds have the potential as HTL material, with DNB and bDNB better than DNP.

Abstract:
Synthetic and biological amines such as ethylenediamine (EDA), spermine, and spermidine have not been previously investigated in free-radical biochemical systems involving aniline-based drugs or xenobiotics. We aimed to study the influence of polyamines in the modulation of aromatic amine radical metabolites in peroxidase-mediated free radical reactions. The aniline compounds tested caused a relatively low oxidation rate of glutathione in the presence of horseradish peroxidase (HRP), and H2O2; however, they demonstrated marked oxygen consumption when a polyamine molecule was present. Next, we characterized the free-radical products generated by these reactions using spin-trapping and electron paramagnetic resonance (EPR) spectrometry. Primary and secondary but not tertiary polyamines dose-dependently enhanced the N-centered radicals of different aniline compounds catalyzed by either HRP or myeloperoxidase, which we believe occurred via charge transfer intermediates and subsequent stabilization of aniline-derived radical species as suggested by isotopically labeled aniline. Aniline/peroxidase reaction product(s) were monitored at 435 nm by kinetic spectrophotometry in the presence and absence of a polyamine additive. Using gas chromatography – mass spectrometry, the dimerziation product of aniline, azobenzene, was significantly amplified when EDA was present. In conclusion, di- and poly-amines are capable of enhancing the formation of aromatic-amine-derived free radicals, a fact that is expected to have toxicological consequences.

Abstract:
A bacterial consortium comprising four different species was isolated from an Indonesian agricultural soil using a mixture of aniline and 4-chloroaniline (4CA) as principal carbon sources. The four species were identified as Chryseobacterium indologenes SB1, Comamonas testosteroni SB2, Pseudomonas corrugata SB4 and Stenotrophomonas maltophilia SB5. Growth studies on aniline and 4CA as single and mixed substrates demonstrated that the bacteria preferred to grow on and utilize aniline rather than 4CA, although both compounds were eventually depleted from the culture supernatant. However, despite 100 % disappearance of the parent substrates, the degradation of 4CA was always characterized by incomplete dechlorination and 4-chlorocatechol accumulation. This result suggests that further degradation of 4-chlorocatechol may be the rate-limiting step in the metabolism of 4CA by the bacterial consortium. HPLC-UV analysis showed that 4-chlorocatechol was further degraded via an ortho-cleavage pathway by the bacterial consortium. This hypothesis was supported by the results from enzyme assays of the crude cell extract of the consortium revealing catechol 1,2-dioxygenase activity which converted catechol and 4-chlorocatechol to cis,cis-muconic acid and 3-chloro-cis,cis-muconic acid respectively. However, the enzyme had a much higher conversion rate for catechol [156 U (g protein)−1] than for 4-chlorocatechol [17·2 U (g protein)−1], indicating preference for non-chlorinated substrates. Members of the bacterial consortium were also characterized individually. All isolates were able to assimilate aniline. P. corrugata SB4 was able to grow on 4CA solely, while S. maltophilia SB5 was able to grow on 4-chlorocatechol. These results suggest that the degradation of 4CA in the presence of aniline by the bacterial consortium was a result of interspecies interactions.

Abstract:
Infrared spectra of benzylidene aniline, p-nitrobenzylidene aniline, p-N-dimethylaminobenzylidene aniline, and their 15N-labelled azomethine analogs were obtained to assess the reliability of C=N stretching assignments and Hammett relationships based on these results. The isotopic data indicate that there is extensive mixing of internal coordinates in bands near 1600 cm−1. Bands possessing the greatest C=N stretching character are not always readily distinguishable from aromatic ring breathing modes due to variations in relative intensities and band overlap. Problems related to the use of frequency and intensity data of highly coupled normal modes in Hammett correlations are discussed.

Abstract:
The Schiff-base compounds 2,4-di-tert-butyl-6-(((3,4,5-trimethoxyphenyl)imino)methyl)phenol (L1H), 2,4-di-tert-butyl-6-(((2,4,6-trimethoxyphenyl)imino)methyl)phenol (L2H), 2,4-di-tert-butyl-6-(((2,4-trimethoxyphenyl)imino)methyl)phenol) (L3H) derived from anilines bearing methoxy substituents have been employed in the preparation of alkylaluminum and zinc complexes. Molecular structure determinations reveal mono-chelate aluminum complexes of the type [Al(Ln)(Me)2] (L1, 1; L2, 2; L3, 3), and bis(chelate) complexes for zinc, namely [Zn(Ln)2] (L1, 5; L2, 6; L3, 7). All complexes have significant activity at 50 °C and higher activity at 100 °C for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) with good control over the molar mass distribution (Mw/Mn < 2) and molecular weight. Complex 1 was found to be the most active catalyst, achieving 99% conversion within 18 h at 50 °C and giving polycaprolactone with high molecular weight; results are compared against aniline-derived (i.e., non-methoxy containing) complexes (4 and 8). Aluminum or zinc complexes derived from L1 exhibit higher activity as compared with complexes derived from L2 and L3. Complex 1 was also tested as an initiator for the copolymerization of ε-CL and glycolide (GL). The CL-GL copolymers have various microstructures depending on the feed ratio. The crosslinker 4,4′-bioxepane-7,7′-dione was used in the polymerization with ε-CL using 1, and well-defined cross-linked PCL was afforded of high molecular weight.

Abstract:
Ce travail se situe dans le cadre de l'application des polymeres conducteurs electroniques (pce) aux batteries rechargeables. L'objectif a ete d'associer deux partenaires aux proprietes electrochimiques complementaires: un pce, la polyaniline, connue pour sa bonne tenue a la charge permanente, une autodecharge faible et une cyclabilite elevee en batterie, et un systeme electroactif base sur le couple redox disulfure/dithiolate qui presente une forte densite d'energie massique. Trois voies ont ete successivement explorees: - la preparation d'une polyaniline substituee sur le cycle par un groupement thiol. L'homopolymere n'a pu etre synthetise simplement car la forme oxydee radicalaire de la dithiodianiline s'adsorbe a la surface des electrodes ou se suroxyde. Nous avons plutot prepare un copolymere aniline-dithiodianiline par voie chimique. Malheureusement, le copoly(aniline-dithiodianiline) n'est pas conducteur et les proprietes electrochimiques des 2 partenaires ne sont ni additives, ni compatibles. - le melange en composite moleculaire pani-polydimercaptothiadiazole (polydmct): ce polydisulfure constitue une electrode reversiblement electropolymerisable qui possede une remarquable densite coulombique massique mais une mauvaise cyclabilite liee a la diffusion des especes thiolates dans l'electrolyte et passivation du metal dans les batteries lithium. Nous avons pu determine la composition optimale de chaque constituant a partir de tests en batteries lithium. La capacite maximale atteinte est 117 ah/kg sous 1 ma cm-2 mais la mauvaise cyclabilite electrochimique du polydmct n'a pas ete resolue. - la fonctionnalisation d'une polyaniline sur l'azote par un groupement carbodithioate: l'action du disulfure de carbone sur une solution de pani sous forme leucoemeraldine permet de greffer environ 80% des azotes en conservant une bonne conductivite (1 s. Cm-1). Le materiau obtenu presente une capacite d'echange accrue de 68% par rapport a la pani de depart.

The objectives of this work were: the preparation of different forms of carbon materials (AC, ACSA, CX, CXSA and GBCM), assessment of their catalytic efficiency in the CWPO of the azo dye Chromotrope 2R. Initially the materials were characterized by several techniques, afterwards adsorption and reaction runs were done and lastly the samples obtained from the adsorption/reaction runs were tested using the COD to calculate the organic matter in solution. Reactions were carried out with 100 mg/L C2R solution at 50ºC, pH = 3, hydrogen peroxide of 34.6 mM (5 mL) and 0.5 g/L of carbon material. Several samples (5 mL) were removed from the reactor during 2.5 hours to evaluate the evolution of the dye removal by analysis with UV-VIS (spectrophotometer). The adsorption runs were done the same way, but without hydrogen peroxide. The best results were obtained with Activated Carbon, this material was the best adsorbing material and catalyst, removing 64 % of C2R after 150min of reaction and 74 % the adsorption run. As the reaction results weren´t better than the adsorption ones, iron was incorporated in two of the materials. Incorporating iron in the carbon materials increased radically their catalytic behaviour, with 100 % removal being attained after 150 min of reaction. Os objectivos deste trabalho foram: a preparação de diferentes materiais de carbono (AC, ACSA, CX, CXSA e GBCM) e testar a eficiência destes no CWPO do corante Chromotrope 2R. Inicialmente os materiais foram caracterizados através de várias técnicas, seguidamente foram realizados os ensaios de adsorção e reacção, e no fim, determinou-se a Carência Química do Oxigénio (CQO) das amostras resultantes dos ensaios. As reacções foram feitas numa solução de Chromotrope a 100 mg/L, a 50º C, pH = 3, peróxido de hidrogénio a 34.6 mM (5 mL) e com 0.5 g/L de material de carbono. Foram retiradas várias amostras (5 mL) do reactor durante 2.5 horas, para avaliar a evolução da degradação do corante através da análise com UV-VIS (espectrofotómetro). Os ensaios de adsorção foram feitos da mesma forma, mas sem o peróxido de hidrogénio. Os melhores resultados foram obtidos com o carvão activado que foi o melhor adsorvente e catalisador, removendo 64 % do Chromotrope após 150 min de reacção e 74 % no ensaio de adsorção. Como os resultados da reacção não foram melhores que os obtidos da adsorção, foi incorporado ferro em dois dos materiais. A incorporação de ferro nos materiais de carbono aumentou radicalmente o comportamento catalítico destes, obtendo-se uma remoção de 100 % após 150 min de reacção.

Abstract:
Ce travail est consacre a l'etude des proprietes de transport, conductivite et pouvoir thermoelectrique, de plusieurs polymeres conducteurs electroniques. Le suivi de l'evolution de ces proprietes en fonction d'un seul parametre de structure, a savoir: le desordre cree par le vieillissement dans le polypyrrole ou dans la polyaniline protonee a l'acide camphre sulfonique, le taux de reticulation dans des reseaux a base de polyoctylthiophene, ou la composition dans des composites polyaniline-nafion ou polyaniline-polyoxyde d'ethylene, nous a permis de preciser la nature du processus de conduction dans chacun de ces materiaux, et de degager des caracteristiques communes a ces systemes. Dans les polymeres conducteurs tres desordonnes, on observe un processus de sauts limite par l'energie de charge entre ilots conducteurs polaroniques separes par des barrieres isolantes. Nous montrons que la variation thermique de la conductivite observee experimentalement peut etre obtenue par des simulations numeriques a partir de methodes de milieu effectif. Dans les reseaux de polyoctylthiophene, une correlation est fortement suggeree entre ilots conducteurs et ilots cristallins. Dans les melanges a base de polyaniline, les ecarts observes par rapport a la theorie classique de la percolation sont attribues a ces processus de hopping. Pour des niveaux de conduction croissants, interviennent un effet tunnel entre gros ilots induit par les fluctuations thermiques puis des processus de conduction de type metallique, lies a la structure interne des grains conducteurs et de nature quasi-unidimensionnel. Les mesures de pouvoir thermoelectrique confirment cette image heterogene de la structure. De facon generale, a un terme lineaire en fonction de la temperature, de type metallique, se superpose, une contribution de type semi-conducteur amorphe. Dans les polymeres conducteurs, c'est la microstructure, les heterogeneites de dopage ou les zones plus ou moins cristallines qui determinent en premier lieu les proprietes de transport macroscopiques. La structure locale des chaines intervient dans les processus de conduction a l'interieur des ilots conducteurs et en filigrane dans les proprietes de transport macroscopiques. Dans cette perspective, le vieillissement peut etre decrit comme un grignotage d'ilots conducteurs au profit de barrieres isolantes

Abstract:
Solid catalysts by their very nature involve diffusion of reactant fluids within their matrix. These fluids react even as they diffuse. Thus the problem of internal diffusion accompanied by reaction becomes important. Another problem of equal importance is the transport of the reactant from the fluid bulk to the catalyst surface—often referred to as external diffusion. Together these constitute the microenvironment of the catalyst pellet and form the subject matter of this chapter. Consider the reaction between aniline and methanol on pellets of alumina to give dimethylaniline: Let the pellets be placed in a flowing stream of reactants inside a tubular reactor. Restricting our attention now to a single pellet and its immediate environment, the various steps involved in the overall process are shown in Figure 7.1. This physical-chemical circuit is built in analogy with the electrical circuit shown at the bottom of the figure. Clearly, the overall process is a complex combination of chemical and physical steps. Note, however, that the mathematical analysis of the parallel pathways (diffusion and reaction) is not always based on the addition of reciprocal resistances as in parallel electrical circuits but on the fact that the two occur simultaneously on a single pathway, that is, the molecule reacts even as it diffuses. The construction of a model based on one of the adsorption-reactiondesorption steps being the limiting step constitutes the core of the semiempirical approach considered in this chapter. In this approach, the microscopic origins of the observed macroscopic effects of catalysts (as described by many authors, e.g., Plath, 1989) are ignored. The models thus developed are commonly known as Langmuir-Hinshelwood models among chemists and as Hougen-Watson models among chemical engineers. We choose to call them Langmuir-Hinshelwood-Hougen-Watson (LHHW) models. For a more basic approach to kinetic modeling of catalytic reactions in general, reference may be made, among others, to Compton (1991) and Van Santen and Niemantsverdriet (1995). In the interest of generality, we consider hypothetical reactions and derive rate equations for a few typical LHHW models (Hougen and Watson, 1947; Yang and Hougen, 1950; Satterfield, 1980, Butt, 1980; Doraiswamy and Sharma, 1984; Boudart and Djéga-Mariadassou, 1984)..

Abstract:
Keiji Maruoka of Kyoto University (J. Am. Chem. Soc. 2009, 131, 3450) and Yujiro Hayashi of the Tokyo University of Science (Chem. Commun. 2009, 3083) independently developed organocatalysts for the enantioselective α-benzoylation of aliphatic aldehydes such as 1. The product 3 can be readily carried on to, inter alia, either enantiomer of the epoxide. Chengjian Zhu of Nanjing University designed (Adv. Synth. Cat. 2009, 351, 920) a chiral salen complex that mediated the enantioselective opening of both cyclohexene oxide (4) and cyclopentene oxide. This reagent combination might also engage just one of the two enantiomers of a racemic cycloalkene epoxide. Lin Pu of the University of Virginia established (Organic Lett. 2009, 11, 2441) a BINOL catalyst for the addition of ethyl propiolate 7 to an aliphatic aldehyde 6 to give the alcohol 8 in high ee. In a complementary approach, Do Hyun Ryu of Sungkyunkwan University found (Angew. Chem. Int. Ed. 2009, 48, 4398) that an oxazaborolidinium salt catalyzed the addition of 7 to 9 to give 10 with high ee and high geometric control. Jianliang Xiao of the University of Liverpool devised (J. Am. Chem. Soc. 2009, 131, 6967) an Ir catalyst for the enantioselective reductive amination of a ketone 11 to the amine 13 . Karl B. Hansen, Yi Hsiao. and Feng Xu, then all at Merck/Rahway, showed (J. Am. Chem. Soc. 2009, 131, 8798) that it was possible to hydrogenate a vinylogous primary amide 14 to the amine 15 with high enantiocontrol. Takashi Ooi of Nagoya University designed (J. Am. Chem. Soc. 2009, 131, 7242) a chiral P-spiro tetraaminophosphonium catalyst that mediated the enantioselective addition of anilines to nitroalkenes such as 16. The product 18 could be carried on to the 1,2-diamine, or to the α-amino acid. Masahiro Terada of Tohoku University devised (Angew. Chem. Int. Ed. 2009, 48, 2553) a BINOL-derived phosphonic acid to catalyze the enantioselective 1,2-addition of the enamide 20 to the imine derived from 19. Yixin Lu of the National University of Singapore found (Organic Lett. 2009, 11, 1721) that a cinchona alkaloid-derived thiourea effectively catalyzed the enantioselective conjugate addition of nitroalkanes such as 22 to the acceptor 23.

Abstract:
Erick M. Carreira at ETH Zürich reported (Science 2013, 340, 1065) the enantiose­lective α-allylation of aldehyde 1 with alcohol 2 to produce 3 using a dual catalytic system involving a chiral iridium complex and amine 5. This stereodivergent method allows access to all of the possible stereoisomers of 3. In a conceptually related proc­ess, John F. Hartwig at the University of California, Berkeley reported (J. Am. Chem. Soc. 2013, 135, 2068) the highly stereoselective allylic alkylation of azlactone 6 with allylic carbonate 7 catalyzed by a combination of Ir(cod)Cl₂, ligand 9, and racemic silver phosphate 10. An enantioselective three-component Mannich-type reaction of tert-butyl diazo­acetate, aniline, and imine 11 to produce α,β-bis(arylamino) acid derivative 13 under dual catalysis with Rh₂(OAc)₄ and acid 12 was developed (Synthesis 2013, 45, 452) by Wenhao Hu at the Shanghai Engineering Research Center of Molecular Therapeutics and New Drug Development. Keiji Maruoka at Kyoto University reported (Chem. Commun. 2013, 49, 1118) a one-pot cross double-Mannich reaction of acetylalde­hyde 14, and imines 16 and 17 using axially chiral amino sulfonamide 15 to obtain densely functionalized 1,3-diamine 18 as a single stereoisomer. Jeffrey S. Johnson at the University of North Carolina at Chapel Hill reported (Org. Lett. 2013, 15, 2446) the asymmetric synthesis of enantioenriched anti-α-hydroxy-β-amino acid derivative 21 from 19 by treatment with oxone followed by catalytic hydrogenation using Ru(II) complex 20. Naoya Kumagai and Masakatsu Shibasaki at the Institute of Microbial Chemistry found (Org. Lett. 2013, 15, 2632) that a sil­ver complex of bisphosphine 24 effected a syn-selective and highly enantioselective Mannich-type reaction of aldimine 22 and α-sulfanyl lactone 23 to furnish the stereo­diad 25 with very high ee. The enantioselective homocrotylation of octanal 26 with cyclopropylcarbinylbo­ronate 27 to produce alcohol 28 with high ee was disclosed (J. Am. Chem. Soc. 2013, 135, 82) by Isaac J. Krauss at Brandeis University with computational studies pro­vided by Kendall N. Houk at UCLA. Benjamin List at the Max-Planck-Institut für Kohlenforschung reported (J. Am. Chem. Soc. 2013, 135, 6677) the enantioselective epoxidation of cyclohexenone 29 utilizing cinchona alkaloid- derived catalyst 30.

Abstract:
John F. Hartwig of the University of California, Berkeley devised (Science 2014, 343, 853) conditions for the regioselective silylation of an arene 1 to give 2. The silyl group can directly be converted, inter alia, to halo, amino, alkyl, or hydroxyl. Jin-Quan Yu of Scripps La Jolla effected (Angew. Chem. Int. Ed. 2014, 53, 2683) regioselective alkenylation of the arene 3 with 4 to give 5. Wei-Liang Duan of the Shanghai Institute of Organic Chemistry described (Org. Lett. 2014, 16, 500) a related alkenyl­ation protocol. Deping Wang of Henyang Normal University developed (Eur. J. Org. Chem. 2014, 315) inexpensive conditions for the conversion of an aryl bromide 6 to the corre­sponding phenol 7. Mamoru Tobisu and Naoto Chatani of Osaka University used (J. Am. Chem. Soc. 2014, 136, 5587) a Ni catalyst to convert the lactam 8 to the aryl boro­nate 9. Patrick J. Walsh of the University of Pennsylvania found (Adv. Synth. Catal. 2014, 356, 165) conditions for the clean monoarylation of the amide 11 with 10 to give 12. In an application of the Catellani approach, Zhi- Yuan Chen of Jiangxi Normal University coupled (Chem. Eur. J. 2014, 20, 4237) the aryl iodide 13 with 14 to give the amino ester 15. Frederic Fabis of the Université de Caen-Basse-Normandie used (Chem. Eur. J. 2014, 20, 7507) Pd to catalyze the ortho halogenation (and alkoxylation) of the N-sulfonylamide 16 to give 17. Wen Wan of Shanghai University and Jian Hao of Shanghai University and the Shanghai Institute of Organic Chemistry effected (Chem. Commun. 2014, 50, 5733) ortho azidination of the aniline 18 with 19, leading to 20. Jianbo Wang of Peking University found (Angew. Chem. Int. Ed. 2014, 53, 1364) that the N-aryloxy amide 21 could be combined with the α-diazo ester 22 to give the ortho-alkenyl phenol 23. Silas P. Cook of Indiana University uncovered (Org. Lett. 2014, 16, 2026) remarkably simple conditions for the enantiospecific cyclization of 24 (65% ee) to 25 (63% ee). The development of arynes as reactive intermediates continues unabated. Xiaoming Zeng of Xi’an Jiaotong University developed (Org. Lett. 2014, 16, 314) the reagent 27 for the bis-functionalization of the aryne derived from 26.
