continuous development of novel and efficient synthetic methods to access these functional groups. Herein, we report an environmentally benign electrochemical method which enables the oxidative coupling between thiols and amines, two readily available and inexpensive commodity chemicals. The transformation is completely driven by electricity, does not require any sacrificial reagent or additional catalysts
磺酰胺是药物和农用化学品中的关键基序,推动了对获取这些官能团的新型有效合成方法的不断开发。在此,我们报告了一种环境友好的电化学方法,该方法可以实现硫醇和胺之间的氧化偶联,这两种容易获得且价格低廉的商品化学品。转化完全由电力驱动,不需要任何牺牲试剂或额外的催化剂,只需5分钟即可完成。氢气在对电极处作为良性副产物形成。由于反应条件温和,该反应显示出广泛的底物范围和官能团兼容性。
