A benzyne-mediated esterification of carboxylic acids and alcohols provides products under mild conditions via a selective nucleophilic addition of carboxylic acid to benzyne in the presence of alcohol followed by a transesterification with alcohol. Benzyne can also be used to promote lactonization and amidation reactions.
