Thioester compounds have been widely applied in the synthesis of bioactive chemicals, natural products and organic materials due to their versatile reactivities. In recent years, the decarboxylation coupling reactions between α-keto acids and thiols/thiophenols have been utilized to access thioesters. Herein, an electrochemical decarboxylation coupling method has been established, which uses α-keto acids and thiophenols as the starting materials and affords thioesters in moderate to good yields. This protocol features simple manipulation and avoids usually needed metal-based catalysts, bases or external oxidants, thus providing a new, mild, and green pathway to synthesize thioester compounds.
