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.

Transition metal-catalyzed cross-electrophilecoupling of two electrophiles has proved to be a powerful and step-economic strategy for the construction of C–Cbonds in organic synthesis. Despite the considerable advances, cross-electrophilecoupling of sp-hybridized carboxylic acid derivatives via a decarbonylative fashion remains a formidable challenge. Herein, we disclose a chemoselective C(sp)–C(sp)
