Transformations of alkynes to carboxylic acids and their derivatives via CC bond cleavage

Abstract

Alkynes are building blocks of high synthetic value and their usefulness as precursors to many chemical and biological systems is widely established. Amongst several transformations of alkynes, cleavage of the CC bond for obtaining diverse compounds is considered to be important. This review, in particular, comprehensively assimilates the transformations of alkynes to carboxylic acids including esters, amides and nitriles resulting from the cleavage of the CC bond either under the influence of a metal catalyst or via a metal-free approach.
