Abstract
The recyclable ionic liquid [ADPQ][CH3COO] has been used as catalyst for aza-Michael addition of amines to α, β-unsaturated compounds to produce β-amino compounds. The reactions were complete in a few hours with high yields. The ionic liquid can be recycled and reused six times without noticeable decrease of catalytic activity.
