摘要
Under Lewis base/photoredox dual catalysis, the defluorinative alkylation of alkylboronic acids with alpha-(trifluoromethyl)styrenes has been reported. In this system, both primary and secondary alkyl radicals produced by alkylboronic acids can react with alpha-(trifluoromethyl)styrenes to generate alkylated gem-difluoroalkenes. In general, the method has mild conditions, a wide substrate scope, and good functional group tolerance, which provides a new route for the synthesis of gem-difluoroalkenes. (C) 2020 Elsevier Ltd.
