Supramolecular assemblies formed by a relay of cooperative hydrogen bonds and charge-charge interactions have been identified/characterized by (+ve) ESI and MALDI-TOF-TOF MS and MS-MS studies during the aza-Michael reaction of amines with alpha,beta-unsaturated carbonyl compounds in the presence of ionic liquids (ILs) digging out the role of catalysis by ILs, forming the basis of rational design/selection as organocatalysts, and offering a diagnostic model to predict/rationalize the selectivity of the aza-Michael reaction in a competitive environment.
