Abstract

Addition reactions O 0060The Ionic Liquid Ethyltri-n-butylphosphonium Tosylate as Solvent for the Acid-Catalyzed Hetero-Michael Reaction. -A new method for the addition of alcohols, thiols and amines to methyl vinyl ketone is developed. The reaction conditions are mild and obviate the need for toxic and expensive Lewis acid catalysts. -(KARODIA*, N.; LIU, X.; LUDLEY, P.; PLETSAS, D.; STEVENSON, G.; Tetrahedron 62 (2006) 48, 11039-11043; Sch.
