Molecular Sieves in Ionic Liquids as an Efficient and Recyclable Medium for the Synthesis of Imines

Abstract

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.
