A mild method of converting arylamines into perfluoroalkylatedarenes is described. Relatively stable RFCu(CH3CN) complexes are used as perfluoroalkylating agents, which react smoothly with arenediazoniumsalts to produce various perfluoroalkylarenes in good yields. Based on the results of clock trapping experiments with diallyl ether, a radical process might be involved in the reaction.

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.
