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

Methods: A total of 180 sodium iodateinduced retinital degeneration rats were randomly divided into three groups, including distilled water group, LDP group, and LDP+Borneolum syntheticum (LDP+BS) group. Twenty normal rats were fed regularly without any treatment as normal control.
