Abstract
A convenient synthesis of various aromatic hydroxyketones via Fries rearrangement is described by condensing a series of aromatic esters with acidic Al2O3-ZnCl2 mixture under microwave conditions. Reactions have been carried out under solvent-free conditions with considerable reduction in reaction time and improvement in yield in comparison to classical methods. The adopted procedure provides an energy and time saving protocol.
