Visible Light‐Mediated Trifluoromethylation of Fluorinated Alkenes via C−F Bond Cleavage

Visible Light‐Mediated Trifluoromethylation of Fluorinated Alkenes via C−F Bond Cleavage

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 alke...

description 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.
