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.

some substituted phenyl perfluoroalkanes to the corresponding ketones. Electron-donating substituents such as -OMe, -OH or -NH2 on the benzene ring, ortho or para to the perfluoroalkyl group, were essential for the conversion to occur under the experimental conditions used. With an electron-donating substituent at the position meta to the perflurooalkyl substituent, only bromination of the aromatic
