Silver-Enabled General Radical Difluoromethylation Reaction with TMSCF2H.

A silver-mediated oxidative difluoromethylation of styrenes and vinyl trifluoroborates with TMSCF 2 H is reported for the first time. This method enables direct and facile access to CF 2 H-alkenes from abundant alkenes with excellent functional group compatibility . Moreover, this Ag/TMSCF 2 H protocol could further enable a series of radical difluoromethylation of a wide array of substrates, offering a generic and complementary platform for the construction of diversified C-CF 2 H bonds.
