摘要
一系列 5-oxo-5,6,7,8-tetrahydro-4H-benzo- 的一个壶合成[b ] 经由在房间温度的醛， dimedone 和 malononitrile 的三部件的联合反应的 -pyran 衍生物没有任何催化剂的离子的液体(RTIL ) 被报导了。同时，离子的液体的复用和不同离子的液体的效果也作为反应上的溶剂被调查了。
A one-pot synthesis of a series of 5-oxo-5,6,7,8-tetrahydro-4H-benzo-[b]-pyran derivatives via three-component coupling reactions of aldehydes, dimedone and malononitrilein room temperature ionic liquids （RTILs） without any catalyst has been reported. In the meantime, the reuse of ionic liquids and the effect of different ionic liquids as solvent on the reaction have also been investigated.
