Ionic liquid 1-butyl-3-methylimidazolium bromide ([bmim]Br) efciently accelerates Michael addition of phthalimide and sulfonamides to α,β-unsaturated esters in the presence of K 2 CO 3 under microwave irradiation (MW) to afford N-alkyl derivatives of these compounds in high yields and short reaction times.Keywords: Ionic liquid; N-Alkyl phthalimide; N-Alkyl sulfonamide; Michael addition; Microwave.e-mail: abdolkarimzare@yahoo.com INTRODUCTION The exploitation of ionic liquids as solvents in organic transformations has been reported extensively during the past decade. 1-5 The most useful properties of ionic liquids are the ability to dissolve a wide range of substances, very low vapor pressure, high thermal stability, and the fact that they can be stored for long times without decomposition. Moreover, it is often possible to achieve reactions in ionic liquids that otherwise proceed with great difculty, or even not at all. 1-3 Together with the substitution of common molecular solvents, non-conventional activation methods have been applied as powerful tools to decrease reaction times and to enhance reactivity, mainly microwave irradiation.
