Copper(II) acetylacetonate immobilized in ionicliquids efficiently catalyzes the aza-Michaelreaction of amines with α,β-unsaturated carbonyl compounds to produce the corresponding β-amino carbonyl compounds with great alacrity in excellent yields. The reactions are far more facile than those reported earlier. The recoveredionicliquid phase containing the copper catalyst can be reused for several cycles
