Abstract
A new straightforward and efficient procedure for the palladium/aluminium-cocatalyzed carbonylative synthesis of 2-chloroethyl benzoates from epoxides and aryl iodides has been developed. By using TFBen (benzene-1,3,5-triyl triformate) as the CO source and LiCl as the chloride source, AlCl3-catalyzed regioselective ring-opening of epoxides was merged successfully with the palladium-catalyzed carbonylative cross-coupling of aryl iodides. A variety of the desired 2-chloroethyl benzoates were obtained in moderate to excellent yields with very good substrates compatibility.
