On January 31, 2015, Liu, Hong-Qiang; Liu, Jun; Zhang, Yang-Hui; Shao, Chang-Dong; Yu, Jing-Xun published an article.Quality Control of 2-Chloro-4-nitrobenzoic acid The title of the article was Copper-catalyzed amide bond formation from formamides and carboxylic acids. And the article contained the following:
A highly efficient copper-catalyzed approach to form amide bonds from formamides and carboxylic acids was developed. This protocol shows broad substrate scopes and high yields in the presence of 1 mol% catalyst and 4.0 equivalent formamides. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Quality Control of 2-Chloro-4-nitrobenzoic acid
The Article related to carboxylic acid formamide amidation copper, amide preparation, copper amidation catalyst, Benzene, Its Derivatives, and Condensed Benzenoid Compounds: Amides, Amidines, Imidic Esters, Hydrazides, and Hydrazonic Esters and other aspects.Quality Control of 2-Chloro-4-nitrobenzoic acid
