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.

4-(Rf8CH2CH2)2C6H3I (77-93%). The former, the crystal structure of which is determined, reacts with Cl2 to give a 75:25 ArICl2/ArI mixture, but partial Cl2 evolution occurs upon work-up. The latter gives the easily isolated dichloride 1,2,4-(Rf8CH2CH2)2C6H3ICl2 (89%). The relative thermodynamic ease of dichlorination of these and other iodine(I) compounds is probed by DFT calculations.
