Abstract
An efficient, rapid, and green method was developed for the synthesis of xanthones and azaxanthones. Transition-metal-free intramolecular Ullmann-type O-arylation reaction of 2-halo-2′-hydroxybenzophenones in the presence of TBAOH as base under microwave irradiation in water afforded the desired xanthones and azaxanthones in short reaction time in excellent yields.
