To　achieve　the　stereoselective　and　regioselective　diamination　of　alkenes,　Xu　et　al.　developed　an　electro-chemical　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.　This　work　has　been　published　in　the　Nature　Communications　and　can　be　reached　at　.
