离子液体中芳香醛和丙二酸亚异丙酯的Knoevenagel缩合反应研究

Study on the Knoevenagel Condensation of Aromatic Aldehydes with Meldrum's acid in Ionic liquid

研究了离子液体中芳香醛和丙二酸亚异丙酯之间的Knoevenagel反应,发现在乙二胺二乙酸盐(EDDA)催化下缩合反应能在室温下短时间内顺利完成,产物分离方便,离子液体和固定在其中的催化剂可以循环利用,效果良好。

The Knoevenagel condensation of aromatic aldehydes with Meldrum＇s acid proceeded efficiently at room temperature catalyzed by ethylenediammonium diacetate（EDDA） in inonic liquid, and the ionic liquid containing catalyst could be recycled several times with no decreases in yields and reaction rates.
