McDonald and co-workers reveal this approach to be a rapid and powerful method for accessing a variety of functionalized amines. The material outlined in this book shows how McDonald achieved C−H zincation using strong, non-nucleophilic zinc bases and subsequent electrophilic amination of the corresponding zinc carbanions with copper as a catalyst and O-benzoylhydroxylamines as the electrophilic nitrogen source. McDonald’s findings are of relevance to medicinal chemistry, drug discovery and materials science. Her thesis is a source of inspiration for scientists entering the field and students beginning their PhD in a related area.

Download or read book Iron and Cobalt Catalysts written by Wilson D. Shafer and published by MDPI. This book was released on 2020-06-23 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.

Download or read book Investigations in Iron Copper and Palladium catalyzed C H Bond Functionalization written by Ly Dieu Tran and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal-catalyzed functionalization of C-H bonds has been used as a powerful tool for the construction of C-C and C-heteroatom bonds. Within this dissertation, methods that allow functionalization of C-H bonds via iron and copper catalysis have been developed. Additionally, functionalization of sp3 C-H bonds in amino acid derivatives using auxiliary-assisted palladium-catalyzed methodology is also demonstrated. A method for iron-catalyzed alkylation of arenes and heterocycles containing acidic C-H bonds has been developed. Various heterocycles such as pyridine, furan, thiophene and electron deficient arenes can be coupled with both alkyl bromides and iodides. Magnesium amide base is required for the reaction. Similarly, the deprotonative dimerization of arenes and heterocycles can be effected in the presence of an iron catalyst. Thus, the method allows direct functionalization of arenes and heterocycles. Additionally, the use of an iron catalyst is an advantage compared with existing methods. Methods for copper-catalyzed direct sulfenylation and amination of sp2 C-H bonds have been developed. Using 8-aminoquinoline auxiliary and copper catalyst, ortho C-H bonds of benzoic acid amides can be sulfenylated by disulfides. The method provides an alternative, milder way for the preparation of aryl trifluoromethylsulfides. Furthermore, ortho C-H bonds of benzoic acid amides can be aminated by reaction with simple amines using 8-aminoquinoline directing group and a copper catalyst. Sulfenylation and amination of g-C-H bonds of benzyl amine derivatives using picolinic acid auxiliary were also demonstrated. Broad substrate scope, high regioselectivity, and good functional group tolerance were observed. The use of a copper catalyst and a removable directing group are significant improvements compared with the existing methods. Finally, a novel way for synthesis of non-natural amino acids via auxiliary-assisted, palladium-catalyzed C-H functionalization methodology was developed. Under palladium catalysis, 2-methyl thioaniline auxiliary allows the monoarylation of b-C-H bonds of alanine derivatives generating, after directing group removal, substituted phenylalanines. In contrast, using 8-aminoquinoline auxiliary, methylene groups in phenylalanine, leucine, and lysine derivatives can be arylated. Methods for alkylation and acetoxylation were also reported. The directing group can be removed without significant erosion of enantiomeric excess. The method provides a straight-forward way to synthesize non-natural amino acids from the chiral pool.

Download or read book Mechanistic Insights Into Copper Catalyzed Sp3 C H Functionalization written by Eun Sil Jang and published by . This book was released on 2015 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herein we describe the mechanistic understanding of -diketiminato copper(I) complexes, [CuI], in catalytic intramolecular sp3 C-H functionalization using tBuOOtBu as an oxidant. With initial success in C-H amination using unactivated alkyl and arylamines, H-NR1R2, each step in the proposed catalytic cycle underwent rigorous analysis, largely devoted to understanding the role of -diketiminato copper(II) amide intermediates [CuII]-NR1R2. Previous studies proposed [CuII]-NHAd (Ad = adamantyl) as the intermediate responsible for a key step in our catalysis, capable of performing both hydrogen atom abstraction (HAA) of R-H to give R as well as radical capture (RC) of this alkyl radical R to give R-NHAd and [CuI]. With other copper(II) amides bearing aromatic N-substituents, the role of such [CuII]-NHAr species is primarily to capture the R radical formed via HAA of R-H by •OtBu (released by [CuI] catalyzed homolytic cleavage of tBuOOtBu). This amino variant Kharasch-Sosnovsky reaction has been effectively applied to other functional groups such as alcohols, nitroalkanes, and aryl ketones to introduce new methods for sp3-C-O and sp3-sp3 C-C bond formation.
