A facile synthesis of trifluoromethylated alkenes by the radicalmediated
trifluoromethylation of vinyltrifluoroborates has been
developed. Togni’s reagent serves as a CF3 radical precursor in the
presence of the photoredox catalyst [Ru(bpy)3](PF6)2 under visible
light irradiation. This new photocatalytic protocol can be applicable
to a wide variety of vinylborates containing electronically diverse
substituents and hetero-aromatics.
