摘要: Carboxylic acids, converted in situ into carboxylic-(p-nitrobenzene)sulfonic anhydrides using p-nitrobenzenesulfonyl chloride, Et3N, and DMAP in CH3CN, react with primary or secondary amines, to give amides in high yields.关键词: amide formation, amide hydrolysis ...
Hydrogen bonding between carboxylic acid and amide groups was demonstrated for a series of amides called [n]-semirubins consisting of a dipyrrinone attached to the end of an n-carbon alkanoic acid. Such hydrogen bonding is more effective than the alternative amide to amide or acid to acid ...
such as, for example, 2 - pyrrolidone, succinimide, milk acid amide and fatty acid amides, with hydrogen to the corresponding amines can be hydrogenated... I Shuklov,J Schulze,A Brner,... 被引量: 0发表: 2016年 Biocatalytic amidation of carboxylic acids and their antinemic activity The co...
Unmodified MnO x showed superior activity in the conversion of the hydroxymethyl group as well as the aldehyde group, producing the products of complete ammoxidation of dinitrile and cyanoamide. The product distribution changed once acetic acid was introduced. When the carboxylate concentration increased...

delivering the desired products in yields of up to 97%. Importantly, when the nitroarenes bearing nucleophilic functional groups, such free amino (3uu), hydroxy (3al), NH-free indole (3ao), the amide bond formation between carboxylic acid and nitro groups is still predictable. These are cas...
