A convenient photoredox‐catalyzed defluorinative trifluoromethylation of α‐trifluoromethyl alkenes and gem‐difluoroalkenes is developed. The reactions proceeded efficiently via trifluoromethyl radical addition followed by β‐fluorine elimination process, providing a new entry to multifluorinated alkenes in moderate to good yields with excellent stereoselectivity.

通过C-F键断裂的可见光介导的含氟烯烃的三氟甲基化

开发了一种方便的光氧化还原催化的α-三氟甲基烯烃和宝石-二氟烯烃的脱氟三氟甲基化反应。该反应通过添加三氟甲基自由基和随后的β-氟消除过程有效地进行,从而以中等至良好的收率和优异的立体选择性为多氟化烯烃提供了新的途径。
