Cesium acetate was found to be the best catalyst for the synthesis of 3-benzylidenephthalide from phthalic anhydride and phenylacetic acid. Reasonable to good yields of different 3-arylmethylenephthalides were isolated from the microwave Gabriel synthesis, even when phenylthio- and 2-(3-)thienyl- acetic acids were used as the starting material.
发现乙酸铯是从邻苯二甲酸酐和苯乙酸合成3-苄叉二苯酞的最佳催化剂。即使使用苯硫基和2-(3-)噻吩基-乙酸作为原料,从微波Gabriel合成中也可以分离出具有合理收率的不同3-芳基亚甲基邻苯二甲酸酯。
