Abstract:
Affinity biosensors based on graphene field-effect transistor (GFET) or resistor designs require the utilization of graphene’s exceptional electrical properties. Therefore, it is critical when designing these sensors, that the electrical properties of graphene are maintained throughout the functionalization process. To that end, non-covalent functionalization may be preferred over covalent modification. Drop-cast 1,5-diaminonaphthalene (DAN) was investigated as a quick and simple method for the non-covalent amine functionalization of carbon-based surfaces such as graphene, for use in biosensor

Abstract:
Post-combustion CO2 capture is a promising approach for complementing other strategies to mitigate climate change. Liquid absorption is currently used to capture CO2 from post-combustion flue gases. However, the high energy cost required to regenerate the liquid absorbents is a major drawback for this process. As a result, solid sorbents have been investigated extensively in recent years as alternative media to capture CO2 from flue gases. For example, metal organic frameworks (MOFs) are nanoporous materials that have high surface areas, large pore volumes, and flexible designs. A large number

Abstract:
A classic example of C-H functionalization is the familiar NBS bromination of a benzylic site. Recent updates of this approach allow for direct alkoxylation (J. Am. Chem. Soc. 2008, 130, 7824) and net amination (Organic Lett. 2008, 10, 1863). For the amination of simple aliphatic H’s, Holger F. Bettinger of Ruhr-Universität Bochum developed (Angew. Chem. Int. Ed. 2008, 47, 4744) the boryl azide 2. The insertion with 1 proceeded to give a statistical mixture of the nitrene insertion products 3 and 4. The tethered C-H functionalization devised (J. Am. Chem. Soc. 2008, 130, 7247) by Phil S. Baran of Scripps-La Jolla is selective, as in the conversion to 5 to 6, but appears to be limited to tertiary and benzylic C-H sites. Michael P. Doyle of the University of Maryland established (J. Org. Chem. 2008, 73, 4317) an elegant protocol for the oxidation of an alkyne such as 7 to the ynone 8. Note that the oxidation did not move the alkyne. Marta Catellani of the Università di Parma reported (Adv. Synth. Cat. 2008, 350, 565) the intriguing Pd-catalyzed conversion of 9 to 10. Under mild conditions, it might likely be possible to hydrolyze the vinyl ether to reveal the phenol 11. Another way of looking at this overall transformation would be to consider the ether 10 to be a protected form of the aldehyde 12. C-H activation can also lead to C-C bond formation. Irena S. Akhrem of the Nesmeyanov Institute, Moscow, described (Tetrahedron Lett. 2008, 49, 1399) a hydride-abstraction protocol for three-component coupling of a hydrocarbon 13 , an amine 14 , and CO, leading to the homologated amide 15. Hua Fu of Tsinghua University, Beijing, showed (J. Org. Chem. 2008 , 73, 3961) that oxidation of an amine 16 led to an intermediate that could be coupled with an alkyne 17 to give the propargylic amine 18. Products 15 and 18 are the result of sp2 and sp coupling, respectively. C-H functionalization leading to sp3 -sp3 coupling is less common. Jin-Quan Yu of Scripps/La Jolla found (J. Am. Chem. Soc. 2008, 130, 7190) that activation of the N-methoxy amide 19 in the presence of the alkyl boronic acid 20 gave smooth coupling, to 21.

Abstract:
John F. Hartwig of the University of California, Berkeley showed (Nature 2012, 483, 70) that intramolecular C–H silylation of 1 selectively gave, after oxidation and acetylation, the bis acetate 2. Gong Chen of Pennsylvania State University coupled (J. Am. Chem. Soc. 2012, 134, 7313) 3 with 4 to give the ether 5. M. Christina White of the University of Illinois effected (J. Am. Chem. Soc. 2012, 134, 9721) selective oxidation of the taxane derivative 6 to the lactone 7. Most of the work on C–H functionalization has focused on the formation of C–C, C–O, and C–N bonds. Donald A. Watson of the University of Delaware developed (Angew. Chem. Int. Ed. 2012, 51, 3663) conditions for the complementary conversion of an alkene 8 to the allyl silane 9, a powerful and versatile nucleophile. Kilian Muniz of ICIQ Tarragona oxidized (J. Am. Chem. Soc. 2012, 134, 7242) the enyne 10 selectively to the amine 11. Phil S. Baran of Scripps/La Jolla devised (J. Am. Chem. Soc. 2012, 134, 2547) a protocol for the OH-directed amination of 12 to 13. Professor White developed (J. Am. Chem. Soc. 2012, 134, 2036) a related OH-directed amination of 14 to 15 that proceeded with retention of absolute configuration. Tom G. Driver of the University of Illinois, Chicago showed (J. Am. Chem. Soc. 2012, 134, 7262) that the aryl azide 16 could be cyclized directly to the amine, which was protected to give 17. As illustrated by the conversion of 18 to 20 devised (Adv. Synth. Catal. 2012, 354, 701) by Martin Klussmann of the Max-Planck-Institut, Mülheim, C–H functionalization can be accomplished by hydride abstraction followed by coupling of the resulting carbocation with a nucleophile. Olafs Daugulis of the University of Houston used (Angew. Chem. Int. Ed. 2012, 51, 5188) a Pd catalyst to couple 21 with 22 to give 23 with high diastereocontrol. Yoshiji Takemoto of Kyoto University cyclized (Angew. Chem. Int. Ed. 2012, 51, 2763) the chloroformate 24 directly to the oxindole 25.

Abstract:
Andrew G. Myers at Harvard reported (Angew. Chem. Int. Ed. 2012, 51, 4568) the alkylation of the pseudophenamine amide 1 selectively setting the quaternary stereogenic center of 2. This is an effective replacement for his previously reported pseudoephedrine, now a controlled substance. Amine catalysis has enabled numerous methods for the asymmetric α-functionalization of aldehydes, although α-alkylation remains a significant challenge. David W.C. MacMillan at Princeton developed (J. Am. Chem. Soc. 2012, 134, 9090) an α-vinylation of aldehydes 3 with vinyliodoniums 5, which relied on the “synergistic combination” of the amine catalyst 4 and copper(I) bromide. The stability of the β,γ-unsaturated aldehyde products under the reaction conditions is notable. A procedure for the asymmetric β-vinylation of α,β-unsaturated aldehydes such as 7 was developed (Eur. J. Org. Chem. 2012, 2774) by Claudio Palomo at the Universidad del Pais Vasco in Spain. Amine 8 catalyzed the enantioselective Michael addition of β-nitroethyl sulfone 9 to 7 followed by acetalization and elimination of HNO2 and SO2Ph furnished products such as 10 in high enantiomeric excess. In a conceptually related reaction, a surrogate for acetate as a nucleophile was reported (Chem. Commun. 2012, 48, 148) by Wei Wang at the University of New Mexico and Jian Li of the East China University of Science and Technology. In this case, amine 13-catalyzed Michael addition of pyridyl sulfone 11 to unsaturated aldehyde 12, followed by acetalization and reductive removal of the sulfone, gave rise to the ester product 14 with very high ee. Asymmetric hydroformylation offers a powerful approach for the synthesis of carbon stereocenters, but controlling the regioselectivity of the reaction remains a challenge with many substrate classes. Christopher J. Cobley of Chirotech Technology Ltd. (UK) and Matthew L. Clarke at the University of St. Andrews showed (Angew. Chem. Int. Ed. 2012, 51, 2477) that the mixed phosphine-phosphite ligand “bobphos” 16 (bobphos = best of both phosphorus ligands) provided significant selectivities for the branched hydroformylation products, up to 10:1 b:l in the case of 15. Another major challenge for hydroformylation is to control the regioselectivity of internal olefin substrates.

Abstract:
The compact and highly functionalized Gelsemium alkaloids, exemplified by gelsemine (OHL20060403) and gelsemoxonine 3, offer a substantial challenge. The cytotoxicity of closely related alkaloids adds to the interest in this class. Tohru Fukuyama of the University of Tokyo envisioned (J. Am. Chem. Soc. 2011, 133, 17634) that cyclopropane-accelerated Cope rearrangement of 1 could deliver 2, ready for further functionalization to 3. The starting material for the synthesis was the enantiomerically pure acetate 4, for which a practical synthetic route was developed. Conjugate addition of 5 then proceeded away from the acetoxy group to give, after intramolecular alkylation, the cyclopropane 6. Selective protection of the derived triol 7 led to a monopivalate that was oxidized to the keto aldehyde 8. Condensation with the oxindole 9 followed by silylation then completed the assembly of 1. The trisubstituted alkene of 1 was established as a single geometric isomer. It followed that in the product 2, the oxindole and the bridging ether had the appropriate relative stereochemical arrangement. The product silyl enol ether was deprotected with fluoride to liberate the ketone 2. With 2 in hand, the next challenge was the kinetic installation of the less stable secondary aminated stereogenic center. To this end, the aldehyde 10 was exposed to TMS-CN and DBU. Under the reaction conditions, the alkene of the intermediate β,γ-unsaturated silylated cyanohydrin was brought into conjugation. Kinetic quench with allyl alcohol gave 11 with a 4:1 preference for the desired endo diastereomer 11. Inversion of the carboxyl then led to the protected amine 12. The ketone 12 was formylated under modified Vilsmeier-Haack conditions, first with Bredereck’s reagent 13 and then with oxalyl chloride, leading to the chloro aldehyde 14. The chlorine was removed by selective Pd-catalyzed reduction, and the product aldehyde was exposed to ethyl magnesium bromide followed by IBX to give the ethyl ketone 15. Epoxidation of the α,β-unsaturated ketone proceeded across the expected exo face leading to 16. The deprotected amine then opened the epoxide to establish the aminated quaternary center and complete the synthesis of gelsemoxonine 3.

Huanfeng Jiang at the South China University of Technology developed (J. Am. Chem. Soc. 2013, 135, 5286) the palladium-catalyzed dehydrogenative aminohalogenation of methyl acrylate with aniline 1. A 1,3-hydrogen shift/ chlorination catalyzed by an iridium complex was reported (Angew. Chem. Int. Ed. 2013, 52, 6273) by Belén Martín- Matute at Stockholm University. Robert M. Waymouth discovered (J. Am. Chem. Soc. 2013, 135, 7593) the chemoselective oxidation of polyol 5 by a cationic palladium species. A ruthenium(II) hydride was found to catalyze the conversion of alcohols such as 7 to carboxylic acids using water as the oxygen source as disclosed (Nature Chem. 2013, 5, 122) by David Milstein at the Weizmann Institute of Science in Israel. Susan K. Hanson at the Los Alamos National Laboratory in New Mexico reported (Org. Lett. 2013, 15, 650) the acceptorless dehydrogenation of alcohols catalyzed by cobalt complex 12 to form imines such as 13 upon reaction with an amine. A collabo­ration led by Pedro J. Pérez at the University of Huelva in Spain studied (J. Am. Chem. Soc. 2013, 135, 3887) the oxidation of alkanes under catalysis with copper complex 15, primarily yielding alcohols and ketones, such as in the conversion of cyclohexane (14) to cyclohexanol (16) and cyclohexanone (17). A remarkable symmetry-breaking Wacker oxidation of diene 18 to produce 19 was the key step in the total synthesis of (+)-obolactone reported (Org.

Arumugam Sudalai of the National Chemical Laboratory, Pune reported (Tetrahedron Lett. 2008, 49, 6401) a procedure for hydrocarbon iodination. With straight chain hydrocarbons, only secondary iodination was observed. Chao-Jun Li of McGill University uncovered (Adv. Synth.

The authors suggested that the C-7 acetoxy group may be deactivating the C-14 C-H. C-H bonds can also be converted directly to carbon-carbon bonds. Mark E. Wood of the University of Exeter found (Tetrahedron Lett. 2009, 50, 3400) that free-radical removal of iodine from 10 followed by intramolecular H-atom abstraction in the presence of the trapping agent 11 delivered 12 with good diastereo control. Professor Li observed (Angew. Chem. Int. Ed. 2008, 47, 6278) that under Ru catalysis, hydrocarbons such as 13 could be directly arylated. He also established (Tetrahedron Lett. 2008, 49, 5601) conditions for the direct aminoalkylation of hydrocarbons such as 13, to give 17. Huw M. L. Davies of Emory University converted (Synlett 2009, 151) the ester 4 to the homologated diester 19 in preparatively useful yield using the diazo ester 18, the precursor to a selective, push-pull stabilized carbene. Intramolecular bond formation to an unactivated C-H can be even more selective. Guoshen Liu of the Shanghai Institute of Organic Chemistry developed (Organic Lett. 2009, 11, 2707) an oxidative Pd system that cyclized 20 to the seven-membered ring lactam 21 . Professor Du Bois devised (J. Am. Chem. Soc. 2008 , 130, 9220) a Rh catalyst that effected allylic amination of 22, to give 23 with substantial enantiocontrol. Dalibor Sames of Columbia University designed (J. Am. Chem. Soc. 2009, 131, 402) a remarkable cascade approach to C-H functionalization. Exposure of 24 to Lewis acid led to intramolecular hydride abstraction. Cyclization of the resulting stabilized carbocation delivered the tetrahydropyan 25 with remarkable diastereocontrol.

Abstract:
Masayuki Inoue of the University of Tokyo oxidized (Tetrahedron Lett. 2011, 52, 4654) the alkyl benzene 1 to the nitrate 2, which could be carried on to the amide 5, the nitrile 6, the alcohol 7, or the azide 8. X. Peter Zhang of the University of South Florida developed (Chem. Sci. 2012, 2, 2361) a Co catalyst for the cyclization of 7 to 8. Justin Du Bois of Stanford University reported (J. Am. Chem. Soc. 2011, 133, 17207) the oxidative cyclization of the sulfamate corresponding to 7 using a Ru catalyst. Seongmin Lee of the University of Texas showed (Org. Lett. 2011, 13, 4766) that the oxidative cyclization of 9 gave the amine 10 with high diastereoselectivity. Fabrizio Fabris of the Università di Venezia used (Tetrahedron Lett. 2011, 52, 4478) a Ru catalyst to oxidize 11 to the ketone 12. Ying-Yeung Yeung of the National University of Singapore found (Org. Lett. 2011, 13, 4308) that hypervalent iodine was sufficient to oxidize 13 to the ketone 14. Huanfeng Jiang of the South China University of Technology methoxycarbonylated (Chem. Commun. 2011, 47, 12224) 15 under Pd catalysis to give 16. Professor Inoue found (Org. Lett. 2011, 13, 5928) that the oxidative cyanation of 17 proceeded with high diastereoselectivity to give 18. Mamoru Tobisu and Naoto Chatani of Osaka University activated (J. Am. Chem. Soc. 2011, 133, 12984) 19 with a Pd catalyst to enable coupling with 20 to give 21. Rh-mediated intramolecular insertion is well known to proceed efficiently into secondary and tertiary C–H bonds. A. Srikrishna of the Indian Institute of Science, Bangalore found (Synlett 2011, 2343) that insertion into the methyl C–H of 22 also worked smoothly to deliver 23. The macrocyclic oligopeptide valinomycin 24 has nine isopropyl groups. It is remarkable, as observed (Org. Lett. 2011, 13, 5096) by Cosimo Annese of the Università di Bari and Paul G. Williard of Brown University, that direct oxidation of 24 with methyl(trifluoromethyl) dioxirane in acetone specifically hydroxylated at 8 (45.5%, our numbering), 7 (28.5%), and 6 (26%).

Abstract:
One of the most powerful of alkene transformations is enantioselective epoxidation. Tsutomu Katsuki of Kyushu University has developed (Angew. Chem. Int. Ed. 2007, 46, 4559) a Ti catalyst that with H2O2, selectively epoxidized terminal alkenes with high ee. The same catalyst converted a Z 2-alkene such as 3 into the epoxide. This is significant, because such epoxides are opened with nucleophiles selectively at the less congested center. Novel procedures for alkene functionalization have been put forward. Philippe Renaud of the University of Berne has developed (Adv. Synth. Cat. 2008, 350, 1163) a simple protocol for terminal halogenation, based on catalyzed addition of catecholborane, followed by free radical substitution. Sulfides and selenides were also prepared. H. Zoghlami of the Faculty of Sciences of Tunis has devised (Tetrahedron Lett. 2007, 48, 5645) an oxidative sulfinylation, converting a terminal alkene 7 to the sulfide 8. M. Christina White of the University of Illinois (J. Am. Chem. Soc. 2008, 130, 3316) and Guosheng Liu of the Shanghai Institute of Organic Chemistry (Angew. Chem. Int. Ed. 2008, 47, 4733) independently developed Pd catalysts for the oxidation of a terminal alkene 9 to the terminal allylic amine 10. Shannon S. Stahl of the University of Wisconsin-Madison has established (Organic Lett. 2007, 9, 4331) conditions for the complementary transformation of a terminal alkene 11 to the enamide 12. Douglas B. Grotjahn of San Diego State University has optimized (J. Am. Chem. Soc. 2007, 129, 9592) Ru-catalyzed alkene (“zipper”) migration, effecting the conversion of 13 to 14 and of 15 to 16 . There have been several new observations on alkene cleavage. Marcus A. Tius of the University of Hawaii and Bakthan Singaram of the University of California, Santa Cruz have found (Tetrahedron Lett. 2008, 49, 2764) that epoxides such as 17 are cleaved directly by NaIO4, providing a simple alternative to ozonolysis. Rolando A. Spanevello of the Universidad Nacional de Rosario has extended (Tetrahedron 2007, 63, 11410) unsymmetrical ozonolysis to highly substituted norbornene derivatives such as 19, observing 20 as the only product. Patrick H. Dussault of the University of Nebraska–Lincoln has established (J. Org. Chem. 2008, 73, 4688) that alkene ozonolysis in wet acetone delivered the ketone or aldehyde directly, without reductive workup.

Abstract:
Continuing efforts toward the direct functionalization of aromatic C-H bonds, Nobutaka Fujii and Hiroaki Ohno of Kyoto University described (Chem. Commun. 2009, 3413) a Pd-mediated protocol for the ortho hydroxylation of aryl tetrahydropyrimidines such as 1. To use a boronic acid as an activating/directing group, Michinori Suginome, also of Kyoto University, devised (J. Am. Chem. Soc. 2009, 131, 7502) the pyrazolylpyridyl derivative 3. The product 4 could be returned to the boronic acid or carried on to the borate ester, in each case with recovery of the directing group. Eiichi Nakamura of the University of Tokyo established (Angew. Chem. Int. Ed. 2009, 49, 2925) that ortho arylation of 5 could be accomplished even in the presence of a reactive aryl halide. In a complementary approach, Matthew J. Gaunt of the University of Cambridge developed (Science 2009, 323, 1593) a procedure for C-H arylation of anilides such as 7 that showed good meta selectivity. Mamoru Tobisu and Naoto Chatani of Osaka University have found (Chem. Lett. 2009, 38, 710) for the conversion of aryl ethers such as 9 to the tertiary amine. Masahito Ochiai of the University of Tokushima observed (J. Am. Chem. Soc. 2009, 131, 8392) the remarkable inversion of an arene sulfonamide such as 11 to the protected aniline 12. Matthias Beller of the Universität Rostock established (Angew. Chem. Int. Ed. 2009, 49, 918) a Pd-mediated procedure for the conversion of even a congested aryl halide 13 to the phenol 14. The first C-C bond formations with phenols used very reactive, but expensive, leaving groups such as triflates. With improving ligand design, conditions have been found that work well even with inexpensive mesylates. Now, Zhang-Jie Shi of Peking University (J. Am. Chem. Soc. 2008, 130, 14468) and Neil K. Garg of UCLA (J. Am. Chem. Soc. 2008, 130, 14422), working independently, developed similar procedures for the Ni-mediated arylation of esters such as 15. Both groups found that pivalates worked particularly well. For some highly-substituted benzene derivatives, construction of the aromatic ring can be an economical approach.

Abstract:
Amine-functionalized mesoporous silica has attracted much attention as a promising chemical sorbent for capturing carbon dioxide. It has the combination of several features viz., high adsorption capacity, high selectivity toward CO2, fast kinetics, mild conditions for desorption and should be stable under operating conditions. In this study, a chemical grafting route has been developed to synthesize mesoporous adsorbents with amines functionalization for CO2 capture. The initial silylation step was achieved by grafting of different silane linkers (3-aminopropyl)-trimethoxysilane (APS) and 3-ch

Abstract:
This study focusses on investigating the fatigue crack growth behavior in glass fiber laminates embedded with carbon nanotube membranes consisting of different functional groups. In addition to fatigue behavior, quasistatic tensile properties were analyzed to gain better insight into the mechanical properties of these hybrid glass fiber laminates. It was found that tensile strength of the laminates increased by embedding the carbon nanotube membranes but elastic moduli showed different trends with respect to the type of functionalization that was done on the embedded carbon nanotube membranes.

Abstract:
Magnetic nanofluids can be remotely heated by alternating magnetic field and have significant potential for cancer hyperthermia therapy. The heat generated by magnetic nanoparticles is typically quantified by the specific absorption rate (SAR), which represents the thermal power per unit mass of magnetic material generated in the presence of an alternating magnetic field. During hyperthermia treatment, heat dosage of tumor tissue correlates with slowing tumor growth. The therapeutic ratios of cancer can be increased with the use of biofunctionalized magnetic nanoparticles that have higher SAR
