Metal-Free Visible-Light Radical Iodoperfluoroalkylation of Terminal Alkenes and Alkynes
The organic-dye-catalyzed visible-light-induced iodoperfluoroalkylation of unactivated terminal alkenes and alkynes was explored. This process was found to be effective for the simultaneous introduction of iodide and various perfluoroalkyl groups (including difluoroacetate) to alkenes and alkynes possessing a variety of functional groups. A possible reaction mechanism is proposed. This reaction provides a new, metal-free, green method for the synthesis of perfluoroalkylated compounds.
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.
