A novel visible-light photocatalytic difluoromethylselenolation of aryl amines via generation of aryldiazonium salts was achieved using Se-(difluoromethyl) 4-methylbenzenesulfonoselenoate, which was synthesized for the first time. The reagent is readily accessible and shelf-stable. The metal-free reaction conditions and the broad substrate scope provide a green protocol for the efficient and rapid introduction of the difluoromethylselenylether group.
