Abstract:
Carbon–carbon and carbon–heteroatom coupling reactions are among the most important transformations in organic synthesis as they enable complex structures to be formed from readily available compounds under different routes and conditions. Several metal-catalyzed cross-coupling reactions have been developed creating many efficient methods accessible for the direct formation of new bonds between differently hybridized carbon atoms.During the last decade, much effort has been devoted towards improvement of the sustainability of these reactions, such as catalyst recovery and atom efficiency. Polyethylene glycol (PEG) can be used as a medium, as solid-liquid phase transfer catalyst, or even as a polymer support. PEG has been investigated in a wide variety of cross-coupling reactions either as an alternative solvent to the common organic solvents or as a support for catalyst, substrate, and ligand. In this review we will summarize the different roles of PEG in palladium- and copper-catalyzed cross-coupling reactions, with the focus on Heck, Suzuki–Miyaura, Sonogashira, Buchwald–Hartwig, Stille, Fukuyama, and homocoupling reactions. We will highlight the role of PEG, the preparation of PEGylated catalysts and substrates, and the importance for the reaction outcome and applicability.1 Introduction2 PEG in Heck Reactions3 PEG in Homocoupling Reactions4 PEG in Suzuki–Miyaura Reactions5 PEG in Sonogashira Reactions6 PEG in Buchwald–Hartwig Reactions7 PEG in Stille Reactions8 PEG in Fukuyama Reactions9 PEG in Miscellaneous Cross-Coupling Routes10 Conclusions

Abstract:
AbstractDuring the previous couple of decades, transition-metal (Fe, Co, Cu, Ni, Ru, Rh, Pd, Ag, Au) catalyzed inter- and intramolecular coupling reactions have attracted huge attention for the construction of C–C and C–heteroatom (like C–N, C–P, C–O, C–S, etc.) bonds to synthesize a diverse range of polymers, fine chemicals, and agrochemicals (mainly fungicides, herbicides, and insecticides), as well as biologically and pharmaceutically important organic molecules. Furthermore, the employment of lower cost and easily available metals such as first-row transition-metal salts or metal complexes of Fe, Co, Cu, Ni as catalysts compared to the precious metals such as Pd, Ag, Au in cross-coupling reactions have led to major advances in applications within the fields of synthesis. A number of cross-coupling reactions catalyzed by transition metals have been explored, including Suzuki, Heck, Sonogashira, Stille, Kumada, Kochi, Murahashi, Corriu, and Negishi reactions, as well as carbonylative, decarboxylative, reactions and α-arylations. In this review, we offer a comprehensive summary of the cross-coupling reaction catalyzed by different transition metals from the year 2009 to date.1 Introduction2 Pd-Catalyzed Reactions2.1 C–C Cross-Coupling Reactions2.2 C–N Cross-Coupling Reactions2.3 C–P Cross-Coupling Reactions3 Ni-Catalyzed Cross-Coupling Reactions3.1 C–C Cross-Coupling Reactions4 Cu-Catalyzed Cross-Coupling Reactions4.1 C–C Cross-Coupling Reactions4.2 C–O Cross-Coupling Reactions4.2 C–N Cross-Coupling Reactions4.4 C–P Cross-Coupling Reactions4.5 C–Se Cross-Coupling Reactions4.6 C–S Cross-Coupling Reactions5 Fe-Catalyzed Reactions5.1 C–C Cross-Coupling Reactions5.2 C–S Cross-Coupling Reactions6 Co-Catalyzed Reactions7 Transition-Metal Nanoparticle-Promoted Reactions7.1 Pd Nanoparticles7.2 Cu Nanoparticles8 Miscellaneous Reactions9 Perspectives and Future Directions

Abstract:
Palladium-catalyzed cross-couplings and related reactions have enabled many transformations essential to the synthesis of pharmaceuticals, agrochemicals, and organic materials. A related family of reactions that have received less attention are decarboxylative functionalization reactions. These reactions replace the preformed organometallic precursor (e.g., boronic acid or organostannane) with inexpensive and readily available carboxylic acids for many palladium-catalyzed reactions. This review focuses on catalyzed reactions where the elementary decarboxylation step is thought to occur at a palladium center. This review does not include decarboxylative reactions where decarboxylation is thought to be facilitated by a second metal (copper or silver) and is specifically limited to (hetero)arenecarboxylic acids. This review includes a discussion of oxidative Heck reactions, protodecarboxylation reactions, and cross-coupling reactions among others.1 Introduction2 Oxidative Heck Reactions3 Protodecarboxylation Reactions4 Cross-Coupling Reactions5 Other Reactions6 Conclusion

Abstract:
Alkynoic acids have been widely employed as alkyne and alkene sources in decarboxylative reactions. Alkynoic acid coupling leads to the formation of direct coupling products and cyclized products through sequential reactions. Moreover, homocoupling and multicomponent reactions have been developed. The decarboxylative addition of alkynoic acids generates the corresponding alkene products. A number of synthetic methods are utilized for the preparation of arylpropynoic acids including the Sonogashira coupling and the carboxylation of terminal alkynes. Recently, the use of decarboxylative halogenations has also been reported. This review covers decarboxylative reactions of alkynoic acids reported between 2013 and 2019; further, it is divided into several sections according to the type of reaction.1 Introduction2 Direct Coupling3 Sequential Reactions4 Homocoupling5 Multicomponent Reactions6 Addition7 Halogenations8 Synthesis of Alkynoic Acids9 Conclusion

Abstract:
AbstractThe prospective utilization of abundant, CO2-neutral, renewable feedstocks is driving the discovery and development of new reactions that refunctionalize oxygen-rich substrates such as alcohols and polyols through C–O bond activation. In this review, we highlight the development of transition-metal-promoted reactions of renewable alcohols and epoxides that result in carbon–carbon bond-formation. These include reductive self-coupling reactions and cross-coupling reactions of alcohols with alkenes and arene derivatives. Early approaches to reductive couplings employed stoichiometric amounts of low-valent transition-metal reagents to form the corresponding hydrocarbon dimers. More recently, the use of redox-active transition-metal catalysts together with a reductant has enhanced the practical applications and scope of the reductive coupling of alcohols. Inclusion of other reaction partners with alcohols such as unsaturated hydrocarbons and main-group organometallics has further expanded the diversity of carbon skeletons accessible and the potential for applications in chemical synthesis. Catalytic reductive coupling and cross-coupling reactions of epoxides are also highlighted. Mechanistic insights into the means of C–O activation and C–C bond formation, where available, are also highlighted.1 Introduction2 Stoichiometric Reductive Coupling of Alcohols3 Catalytic Reductive Coupling of Alcohols3.1 Heterogeneous Catalysis3.2 Homogeneous Catalysis4 Reductive Cross-Coupling of Alcohols4.1 Reductive Alkylation4.2 Reductive Addition to Olefins5 Epoxide Reductive Coupling Reactions6 Conclusions and Future Directions

Abstract:
The biaryl unit containing a heteroatom is a key structure in a large number of natural products and π-conjugated organic systems. The cross-couplings can provide powerful methods for the construction of biaryls and heterobiaryls; thus the development of a new coupling method has been intensively studied by synthetic chemists. Therefore, the oxidative biaryl coupling reaction of arenes containing a heteroatom is a significantly attractive, convenient, and straightforward route to the synthesis of biaryls due to its operational simplicity avoiding the preparation of the corresponding halogenated and metallated arenes. In this report, recent progress in the field of metal-free oxidative cross-coupling reactions of aromatic compounds using hypervalent iodine(III) reagents, is presented.1 Introduction2 Cyanation and Halogenation Reactions of Heteroaromatic Compounds3 Biaryl Coupling Reaction of Heteroaromatic Compounds3.1 Regioselective Coupling Reaction of Thiophenes3.2 Cross-Coupling Reaction of Thiophenes3.3 Coupling Reaction of EDOT and Pyrroles3.4 Cross-Coupling Reaction of Pyrroles4 Cross-Coupling Reaction of Anilines5 Cross-Coupling Reaction of Phenols6 Cross-Coupling Reaction of N-Heteroaromatics with Aryl Radicals from Diaryliodonium(III) Salts7 Conclusion

Abstract:
The effects of all kinds of amines on homo-couplings (Glaser reactions) of terminal alkynes promoted by copper salts and the Sonogashira coupling reactions were studied systematically. Diethylamine (2° amine) can serve as an excellent solvent, base and coordination ligand in the oxidative homo-coupling of terminal alkynes and several modified Glaser coupling procedures have been developed which are based on a catalytic amount of cuprous salts (CuI, CuBr or CuCl) with diethylamine systems. Homo-coupling of terminal acetylenes in the Sonogashira reaction could be inhibited by using triethylamine (3° amine) as reaction medium, and the cross-coupling products were formed as the exclusive products.

Abstract:
Sustainable chemical processes are becoming increasingly important in all fields of synthetic chemistry. Catalysis can play an important role in developing environmentally benign chemical processes, and transition metals have an important role to play in the area of green chemistry. In particular, palladium(II) catalysis includes many key features for successful green chemistry methods, as demonstrated by a number of eco-friendly oxidation reactions catalyzed by palladium(II). The aim of the work presented in this thesis was to develop novel and greener palladium(II)-catalyzed coupling reactions. In striving to achieve this aim, the first open-vessel, room-temperature palladium(II)-catalyzed oxidative Heck reaction, using oxygen from the air as the reoxidant of palladium, was developed. In a further investigation of the palladium(II)-catalyzed oxidative Heck reaction, base-free conditions for the transformation were identified and suitable conditions for microwave-assisted oxidative Heck reactions were established. A convenient and low-cost palladium(II)-catalyzed method for the synthesis of styrene derivatives, by coupling arylboranes with vinyl acetate, was developed. The reaction mechanism was studied using ESI-MS, which enabled the detection of cationic palladium intermediates in ongoing productive reactions, and a plausible catalytic cycle was proposed. In an attempt to make the oxidative Heck and the styrene synthesis reactions more attractive from an industrial point of view, conditions for continuous flow synthesis were identified. The results were generally good and rapid synthesis of the desired products was obtained. The first palladium(II)-catalyzed C–P bond-forming Hirao-type reaction, employing arylboranes instead of the commonly used aryl halides, was developed. An ESI-MS study was performed, and a plausible catalytic pathway was suggested. Finally, a novel method for synthesizing aryl ketones from benzoic acids and nitriles, via palladium(II)-catalyzed decarboxylation of the benzoic acids, was established. Further, the reaction mechanism was studied by ESI-MS and a plausible catalytic route presented.

Abstract:
The chemistry of the simple alkyne compounds ethyne (acetylene), propyne (methylacetylene) and 2-butyne (dimethylacetylene) over various palladium catalysts has been studied. Both UHV experiments with single crystal surfaces and microreactor experiments with zeolite supported palladium clusters were performed. A particular emphasis was placed on coupling reactions - the bonding of two or more alkyne molecules. The adsorption and chemistry of propyne on Pd(111) and Au/Pd(111) alloy surfaces has been studied in detail using XPS, AES, LEED, UPS and TDS. Close reference to is made to the chemistry of ethyne on these surfaces, which has been previously investigated. The adsorption configuration of propyne closely resembles that of ethyne. Molecular desorption of propyne is the most efficient process, although coupling to benzene, hydrogenation of propene and decomposition represent significant reaction pathways. Cyclotrimerisation of propyne to trimethylbenzene is activated over Au/Pd(111), but the efficiency of this reaction is much lower than the analogous reaction of ethyne. A less detailed investigation of 2-butyne chemistry provided further comparative data. The adsorption configuration adopted by 2-butyne is more distorted than that of ethyne and propyne. 2-butyne is inactive for coupling on both Pd(111) and Au/Pd(111) alloys. The formation of toluene and xylene by mixed coupling reactions of various combinations of ethyne, propyne and 2-butyne was observed over Au/Pd(111). Formation of tetramethylbenzene and larger methyl benzene products was not observed. Several possible heterocyclic coupling reactions of propyne were investigated, but of these, only the addition of oxygen to form dimethylfuran was observed.

Abstract:
Carbon-carbon (C-C) bond formation is among the most important processes in organic chemistry. Transition metal catalyzed C-C bond formation is an active research area that shows great potential due to high selectivity and relatively mild conditions. In Chapter 1, a new reaction for direct acylation of aryl halides is discussed. Specifically, the catalytic reaction between aryl halides/pseudohalides and aldehydes is explored. The choice of ligand, base, solvent, temperature, catalyst and substrates are important factors for optimizing this catalytic reaction. The various combinations of all these factors have, therefore, been examined by high-throughput screening (HTS) in order to develop the new C-C coupling reaction. In Chapter 2, a new methodology is reported in order to expand the scope of the Kumada-Corriu cross-coupling reaction. The strategy to achieve this goal is mechanistically based, matching oxidative addition rates with the rate of syringe pump addition of the Grignard to minimize the exposure of sensitive groups to the aggressive nucleophile. Aryl chlorides containing esters, amides, nitriles, pyrazines, carbamates, ketones, and other sensitive functionalities are all demonstrated to undergo chemoselective cross-coupling with this technique. The mechanistic reason for the effectiveness of this strategy is uncovered by continuous-infusion ESI-MS studies.

Abstract:
Abstract A hybrid technique to couple hydrodynamics and chemical kinetics calculations in a multi-phase, multi-species, turbulent reacting flow simulation has been developed. It divides a flow simulation into two parts: a reacting flow hydrodynamic simulation with a small but sufficient number of lumped reactions to compute flow field properties followed by a many subspecies (of order 10 to 100) reaction kinetics and transport calculation. This technique has been incorporated in a computational fluid dynamics (CFD) code to predict concentrations of many subspecies in a reacting flow where complex chemical reactions take place, and it can be applied to many applications such as combustors. The application presented in this paper is the flow simulation of a fluid catalytic cracking (FCC) riser reactor. Applying the technique in the FCC riser application has shown that it can be used to identify critical processes and operating parameters including the trends and relationships that are necessary to the improve the quality and quantity of FCC products.

Abstract:
The reaction mechanism of reaction reported by Onodera et al4 was studied in the M06L/Def2SVP level of theory. Two possible reaction products were characterized, named as product a and product b, where product a that was identified in the experimental study is due to a exergonic reaction and product b due to a endoergonic reaction.

Abstract:
A mechanistic model that to provide a quantitative understanding of the interplay of hydrodynamics, heat/mass transfer, and cracking reactions in the feed injection zone of a fluid catalytic cracking (FCC) riser reactor with a single nozzle spray. With the injection of an oil spray into a gas-solid flow, the collision between cold oil droplets and hot catalyst particles results in a strong momentum transfer that affects the spray hydrodynamics in terms of penetration and scattering. It also causes a significant heat transfer giving rise to rapid droplet vaporization and the attendant cooling of the catalyst. The presence of cracking reactions introduces volume expansion, changes in gas composition and volume fraction, and a cooling effect due to endothermicity. Accordingly, we in this study present an analysis of chemically-induced “entrance effects” in an FCC riser with a single nozzle spray. The cracking reaction network is described by a four-lump reaction model, while the ambient gas-solid transport is represented by a dense-phase riser flow. A Lagrangian modeling approach is adopted to track the spray trajectory as cracking reactions proceed. It is shown that cracking reactions play an important role in dictating the spray behavior, reaction and heat/mass transfer characteristics in the feed injection zone of an FCC riser.
