开发了一种环境友好的C-H/S-H交叉偶联电催化方法。该方法能够在无催化剂和无氧化剂的条件下形成C-S键。在不分开的电解条件下，各种芳基/杂芳基硫醇和富电子芳烃以24-99%的产率提供C-S键形成产物。初步的机理研究表明，芳基自由基阳离子中间体的产生是这种转化成功的关键。
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.
