yields using the Aza-Michael-type addition of various amines to vinyl compounds catalysed by a supported ionic liquid incorporating an anionic heteropoly acid. Different catalysts, including Lewisacids, Brønsted acids and heteropoly acids were investigated in which heteropoly acids having dual Brønsted and Lewisacid characteristics were excellent catalysts. The ionic liquid incorporating a polytungstate
