Electrochemically driven regioselective construction of 4-sulfenyl-isochromenones from <i>o</i>-alkynylbenzoates and diaryl disulfides

Abstract

-alkynyl benzoates and diaryl disulfides. This electrochemical process has been accomplished through constant current electrolysis in an undivided cell under external acid, catalyst, oxidant, or metal-free conditions. Owing to this protocol's mild reaction conditions, the products are obtained in good to very good yields, demonstrating a broad substrate scope and functional group tolerance.
