Abstract

Abstract A simple and environmentally benign synthesis of 2-amino-1, 3-selenazoles by microwave irradiation using 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim] BF4) ionic liquid (IL) is described. Acyl halides, phenacyl halides, and α-bromo-β-keto esters easily undergo condensation with selenourea in ([Bmim] BF4) by microwave irradiation to afford the desired products of good purity in excellent yields. The ionic liquid can be easily ...
