    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

    Sulfur is an essential element because it exists widely in proteins. The disulfide bond is an important moiety in many different types of significant organic molecules. A new approach for oxidant‐ and catalyst‐free S−H/S−H cross‐coupling, with hydrogen evolution, to construct unsymmetrical disulfides was developed. Under the conditions of an undivided cell at room temperature, a series of unsymmetrical
