Nitrile Synthesis through Catalyzed Cascades Involving Acid-Nitrile Exchange
Abstract
Irreversible acid-nitrile exchange reactions using both glutaronitrile and (phenylsulfonyl)acetonitrile may be catalyzed by Lewis acids. Whereas a cyclization towards imides displaces the equilibria in the reaction with dinitriles, a decarboxylation step is involved when using the (phenylsulfonyl)acetonitrile.
