Visible Light Induced Oxydifluoromethylation of Styrenes with Difluoromethyltriphenylphosphonium Bromide

摘要

A convenient, visible light induced oxidifluoro-methylation of styrenes was developed. This protocol employs the readily prepared difluoromethyltriphenylphosphonium bromide as the difluoromethylating reagent and alcohols/water as the nucleophiles, affording difluoromethyl(CF2H)-containing alcohols and ethers in moderate to excellent yields.
