Abstract

Abstract Phosphine-free hydrazone such as 1c was found to be an efficient ligand for the copper-catalyzed Goldberg-type N-arylation of amides and Ullmann-type N-arylation of azoles with aryl halides under mild conditions. A variety of N-arylamides and N-arylazoles were synthesized in good to high yields.
