Electrocatalytic Oxidant-Free Dehydrogenative C-H/S-H Cross-Coupling.

Pan Wang1, Shan Tang1, Pengfei Huang1, Aiwen Lei1,2.   

Abstract

An environmentally friendly electrocatalytic protocol has been developed for dehydrogenative C-H/S-H cross-coupling. This method enabled C-S bond formation under catalyst- and oxidant-free conditions. Under undivided electrolysis conditions, various aryl/heteroaryl thiols and electron-rich arenes afforded the C-S bond-formation products in 24-99 % yield. A preliminary mechanistic study indicated that the generation of aryl radical cation intermediates is key to the success of this transformation.
