A method for trifluoromethylation of alkenes has been developed employing visible light photoredox catalysis with CF3I, Ru(Phen)(3)Cl-2, and DBU. This process works especially well for terminal alkenes to give alkenyl-CF3 products with only E-stereochemistry. The mild reaction conditions enable the trifluoromethylation of a range of alkenes that bear various functional groups.

applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CF3I. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with C3F7I and C4F9I. Mechanistic studies revealed that the photoredox catalysis involves an oxidative quenching pathway.
