NIS/TBHP Induced Regioselective Selenation of (Hetero)Arenes via Direct C−H Functionalization

Abstract A simple and efficient method for the regioselective selenation of (hetero)arenes via direct C−H functionalization has been established using NIS and TBHP. The present protocol is compatible with different functional groups, and suitable for various (hetero)arenes and diselenides, efficiently affording the desired products in moderate to excellent yields.
