The use of sulfate additives such as H(2)SO(4) greatly increases the reactivity of palladium catalysts for the cyanation of aryl and heteroaryl chlorides and renders them more robust toward adventitious air. Using this method, a wide variety of aromatic and heteroaromatic nitriles were prepared in high yield. (C) 2010 Elsevier Ltd. All rights reserved.
