Abstrakt: A photoredox/Lewis acid cooperative catalytic system has been developed for the construction of Cvinyl–CRfbonds through the dehydrative difluoroalkylation of benzyl alcohols. A variety of allylic gem-difluorides could be obtained in moderate yields with good to excellent E/Zselectivity. In addition, several control experiments have been explored, and a possible mechanism was proposed for this process.
