A convenient, visible light-induced radical difluoromethylation of aryl-, heteroaryl-, and alkylthiols with difluoromethyltriphenylphosphonium triflate was developed to afford various difluoromethyl thioethers in moderate to excellent yields. The key reaction features include the use of a readily available CF2H radical source, mild reaction conditions, and excellent chemoselective "thiol-difluoromethylation.
