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

摘要

An environmentally friendly electrocatalytic protocol has been developed for dehydrogenative C-H/S-H crosscoupling. This method enabled C-S bond formation under catalyst-and oxidant-free conditions. Under undivided electrolysis conditions, various aryl/heteroaryl thiols and electronrich 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.
