developed the first copper-catalysed direct difluoromethylselenolation of arylboronicacids using Se-(difluoromethyl) 4-methylbenzenesulfonoselenoate as a difluoromethylselenolation reagent. Owing to the cheap and readily accessible reagents, broad substrate scope, and mild reaction conditions, this is an alternative and practical strategy for the synthesis of aryl difluoromethylselenylether.

A novel visible-light photocatalytic difluoromethylselenolation of aryl amines via in situgeneration 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
