Metal-Free Visible Light Hydroperfluoroalkylation of Unactivated Alkenes Using Perfluoroalkyl Bromides

Organic dye-catalyzed visible light induced hydroperfluoroalkylation of unactivated alkenes is described. Hydroperfluoroalkylation proceeds selectively and is applicable for various perfluoroalkyl bromide and alkenes including internal alkenes. The reaction mechanism is discussed, and it is shown that the hydrogen source varies with reaction conditions
