Abstract

A simple metal-ligand cooperative approach enables dehydrogenative functionalization of benzylic alcohols to various substituted quinolines and quinazolin-4(3H)-ones in good yields under relatively mild reaction conditions using simple and easy-to-prepare air-stable Cu(II) complexes featuring redox-active azo-aromatic scaffolds.
