Abstract

A variety of aryl nitriles were prepared in excellent yield from the palladium(II) acetate-catalyzed cross-coupling of aryl triflates and zinc cyanide under microwave irradiation conditions. To facilitate purification, polymer-supported triphenylphosphine was used as the palladium ligand. Comparison to the corresponding thermal conditions revealed much shorter reaction times with comparable yields.
