超声波作用下芳亚甲基丙二酸亚异丙酯的合成

Convenient Synthesis of Arylmethylene Isopropylidene Malonate under Ultrasound Iirradiation

在超声波辐射下 ,以芳香醛、丙二酸亚异丙酯为原料 ,乙醇作溶剂 ,无催化剂作用下合成了芳亚甲基丙二酸亚异丙酯 .该方法操作简便 ,不污染环境 ,产率较高 ,为该类化合物的合成提供了一种有效的新方法 .

The arylmethylene isopropylidene malonates were synthesized by the reactin of aromatic aldehydes with isopropylidene malonate. The condensation reaction was carried out under ultrasound irradiation without any catalyst with excellent yields and short time.
