Abstract
A mild, functional group tolerant palladium-catalyzed carbonylation of aryl chlorides using atmospheric pressure of carbon monoxide allows the preparation of phenyl esters, alkyl esters and carboxylic acids. Phenyl esters are shown to be useful acylating agents, delivering libraries of carbonyl derivatives, including alkyl, allyl and thioesters, under very mild conditions.
