A great variety of imines were efficiently isolated in high yields from the reaction of aldehydes and amines in ionic liquids. The ionic liquids could be recovered and reused for at least five cycles without loss in the yields being a useful alternative to dichloromethane or diethyl ether, which are the commonly used solvents for this reaction.
多种亚胺得以高效地从醛和胺在离子液体中的反应中高产率地分离出来。这些离子液体可被回收并在至少五个循环中重复使用,而产率无明显下降,这为常用的反应溶剂二氯甲烷或乙醚提供了一个有用的替代选择。
