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.

钯/铝催化环氧化物和芳基碘化物羰基合成苯甲酸2-氯乙基酯

已经开发了一种新的简单有效的方法，用于由环氧化物和芳基碘化物进行钯/铝共催化的2-氯乙基苯甲酸酯的羰基化合成。通过使用TFBen（苯甲酸1,3,5-三甲苯酯）作为CO源，使用LiCl作为氯离子源，成功地将AlCl ₃催化的环氧化物的区域选择性开环与钯催化的芳基的羰基交叉偶联合并碘化物。以中等至优异的产率获得了各种所需的2-氯乙基苯甲酸酯，具有非常好的底物相容性。
