Abstract

The ionic liquids functionalized mesoporous materials were prepared and they exhibited high and dramatic catalytic activity in the aza-Michael addition of amines and NH-containing heterocycles to α,β- unsaturated carbonyl compounds. Recycling of the catalyst in these reactions was carried out and the catalyst could be used at least five times without significant loss in activity.

Keywords: Ionic liquids, heterogeneous catalysis, aza-Michael, amine, heterocycles, SBA-15
