Herein we report a nickel-catalyzed aryl addition/intramolecular esterification in a cascade fashion. Under the combination of commercially available nickel precursor and tridentate ligand, the one pot protocol offers a direct, simple and regioselective approach to access 3-aryl phthalide derivatives from two readily available substrates with good efficiency, broad scope as well as satisfactory functional
