hetero-Michael reactions among various oxygen, sulfur, and nitrogen nucleophiles and α,β-unsaturated compounds were carried out in the presence of catalytic amounts of o-benzenedisulfonimide as Brønstedacid organocatalyst. The reaction conditions were very mild, and the yields of target products were good. The catalyst was easily recovered and purified, ready to be used in further reactions. This ability
A new and convenient method for the acid-catalysed Michael addition reactions of alcohols, thiols and amines to methyl vinyl ketone has been developed using the ionic liquid ethyltri-n-butylphosphonium tosylate. The reaction conditions are mild and obviate the need for toxic and expensive Lewis acid catalysts, offering advantages over more commonly used systems.
