Treatment of perfluoroalkyl chlorides (R(F)Cl) with alkenes, alkynes, or aromatics in the presence of 0.1 equiv of nickel dichloride, 1.5 equiv of zinc powder, and 0.4 equiv of triphenylphosphine in DMF at 95-100 degrees C for 6-8 h give the corresponding perfluoroalkylated products in good yields. A single electron-transfer mechanism is suggested.

10-Phenylphenothiazine-Organophotocatalyzed Bromo-Perfluoroalkylation of Unactivated Olefins
this study, we have developed a smooth metal-free visible-light-induced bromo-perfluoroalkylation of unactivatedolefins with the aid of 10-phenylphenothiazine (PTH) as an organic photoredox catalyst. The reaction is 100% atom-economic redox-neutral and proceeds with stoichiometric amounts of olefin and perfluoroalkyl bromide. To show the potential of these unexplored motifs, we carried out various

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.
