Abstract: To achieve the stereoselective and regioselective diamination of alkenes, Xu et al. developed an electrochemical protocol for the diamination of aryl alkenes with sulfamides by using triarylamine as a redox mediator. The chemistry proceeded in an undivided cell under constant current conditions, featuring not only wide scope of substrates and reasonable yields, but also excellent diastereoselectivity(>20:1 dr) and regioselectivity.
