The N-arylation of primary and secondary aliphatic amines, anilines, and imidazoles with novel potassium aryl triolborates was carried out in the presence of a reoxidant and a catalytic amount of Cu(OAc)2 (10 mol %). Aryl triolborates were found to be better reagents than arylboronic acids or potassium aryl trifluoroborates as the former achieved high yields under mild conditions. Coupling of primary and secondary aliphatic amines to give N-arylamines in excellent yields was performed under oxygen atm. The reactions of anilines and imidazoles to provide N-arylanilines and N-arylimidazoles in good yields proceeded smoothly when trimethylamine N-oxide was used as an oxidant.
