Abstract

Direct benzylation of carboxylic acids with toluene has been developed via palladium- catalyzed C–H acyloxylation under 1 atm of oxygen. This reaction demonstrates good functional group tolerance and high yields, providing a facile, atom-economic, and efficient method for the synthesis of benzyl esters.
