Formation of C(sp2)–S bonds through decarboxylation of α-oxocarboxylic acids with disulfides or thiophenols†
Abstract
Copper-catalyzed decarboxylative coupling between α-oxocarboxylic acids and diphenyl disulfides or thiophenols is presented, which provided an effective and direct approach for the preparation of useful thioesters through C(sp2)–S bond formation.
