Facial Synthesis of Sulfinic Esters via Copper-Catalyzed Reaction of Sulfonyl Hydrazides with Alcohols in Air

Publication date: Available online 10 July 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Lingjuan Chen, Jiangxin Pu, Ping Liu, Bin DaiAbstractThe efficient Cu-catalyzed esterification of sulfonyl hydrazides with alcohols in air is described, providing sulfinic esters in good yields and broad scope. Mechanistic studies suggest that the reaction likely proceeds through free-radical formation including arylthio radical and arylsulfonyl radical, while arylsulfuric acid are the major esterification intermediate in this transformation.
