Nickel-Catalyzed Esterification of Aliphatic Amides. [PDF]

open access: yesAngew Chem Int Ed Engl, 2016
AbstractRecent studies have demonstrated that amides can be used in nickel‐catalyzed reactions that lead to cleavage of the amide C−N bond, with formation of a C−C or C−heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene.

Nickel-catalysed retro-hydroamidocarbonylation of aliphatic amides to olefins [PDF]

open access: yesNature Communications, 2017
Converting the normally highly stable amide bond into different functionalities is a challenging task. Here the authors report a nickel-catalysed retro-hydroamidocarbonylation procedure, allowing the conversion of aliphatic amides into alkenes across a ...

Nickel-Catalyzed Suzuki-Miyaura Coupling of Aliphatic Amides. [PDF]

open access: yesACS Catal, 2018
We report the Ni-catalyzed Suzuki-Miyaura coupling of aliphatic amide derivatives. Prior studies have shown that aliphatic amide derivatives can undergo Ni-catalyzed carbon-heteroatom bond formation but that Ni-mediated C-C bond formation using aliphatic amide derivatives has remained difficult. The coupling disclosed herein is tolerant of considerable

General and selective ruthenium-catalyzed hydrogenation of primary amides to primary amines under mild conditions [PDF]

open access: yesNature Communications
The catalytic hydrogenation of amides continues to be one of the most difficult reductive transformations in organic synthesis. Despite significant efforts in past decades, there is no general protocol reported allowing the synthesis of various primary ...

The Uptake of Aliphatic Amides by Pseudomonas Aeruginosa [PDF]

open access: yesJournal of General Microbiology, 1966
SUMMARY: The uptake of aliphatic amides by Pseudomonas aeruginosa 8602 was studied by using 1-14C-acetamide and 1-14C-N-acetylacetamide (a non-metabolizable analogue). 1-14C-acetamide was accumulated by the wild-type strains and by an amidase-negative mutant. The maximum ratio of internal to external concentration measured was 100:1.

Cu-Catalyzed Arylation of Bromo-Difluoro-Acetamides by Aryl Boronic Acids, Aryl Trialkoxysilanes and Dimethyl-Aryl-Sulfonium Salts: New Entries to Aromatic Amides

open access: yesMolecules, 2021
We describe a mechanism-guided discovery of a synthetic methodology that enables the preparation of aromatic amides from 2-bromo-2,2-difluoroacetamides utilizing a copper-catalyzed direct arylation.
