A mild and simple three-component procedure for the direct vicinal halotrifluoromethylation
of styrenes and aliphatic alkenes has been developed in the presence of [Ru(bpy)3](PF6)2 as a photosensitizer and Umemoto’s reagent as the CF3 source. The multicomponent method offers the advantage of short reaction time, moderate
to good yields, and mild reaction conditions.
