Under an atmosphere of oxygen and a catalytic amount of Cu(OAc)2, pentafluorophenylboronic acid reacted with anilines at room temperature to produce the corresponding N-pentafluorophenylanilines in moderate to good yields. In the case of alkylamines, unexpected N-alkyl-2,2′,3,3′,4′,5,5′,6,6′-nona-fluoro-biphenyl-4-amines were formed under the similar conditions in moderate yields.
