The acidic ionic liquid, 1-(4-sulfonic acid) butyl-3-methylimidazolium hydrogen sulfate [MimC4SO3H]HSO4 catalyzed two-component condensation reaction of phenacyl bromide and o-phenylenediamine to afford corresponding quinoxaline derivatives. The inexpensive and non-toxic ionic liquids can be reused several times without any perceptible loss of their activities.

Using phosphomolybdic acid on silica as recyclable catalyst we have developed methodology for the synthesis of quinoxalines by condensation of phenacyl bromides and o-phenylene diamines in ClCH2CH2Cl at 80°C. The phosphomolybdic acid
