An efficient electrochemical nickel-catalyzed cross-coupling reaction has been reported here for the synthesis of S-glycosides from preactivated phenols and ketones under mild conditions. Various glycosyl thiols, including unprotected sugar, and a diverse range of aryl/alkenyl triflates, including some complex biorelevant phenols and ketones, were well tolerated in this method.

for the synthesis of aryl thioglycosides from the aryl thianthrenium salts and 1‐thiosugars is achieved by copper(I)‐mediated, photoredox‐catalyzed reactions. The desired products could be obtained in 32% to 78% yield after irradiation with 34 W blue light at room temperature. Various functional groups, especially including halogen groups, were well tolerated under standard reaction conditions. This strategy
