We report the visible-light-induced Ph3P/LiI-promoted intermolecular cascade trifluoromethylradical addition/5-exo-dig cyclization/iodination of 1,6-enynes with Togni’s reagent using LiI as the iodine source without the need of the transition metal, oxidant, and base. This reaction promises to be a useful method for the preparation of trifluoromethyl-substituted and vinyl C–I bond-containing pyrrolidines
