IONIC LIQUID-ACCELERATED SYNTHESIS OF SOME N-ALKYL DERIVATWES OF PHTHALIMIDE AND SULFONAMIDES

Ionic liquid l-butyl-3-methylimidazolium bromide ([bmim]Br) efficiently accelerates Michael addition of phthalimide and sulfonamides to α, -unsaturated esters inthe presence of K2C0(3) under microwave irradiation (MW) to afford W-alkyl derivatives of these compounds in high yields and short reaction times.
