摘要: An efficient and inexpensive sulfated polyborate catalyst was applied for the rapid synthesis of quinoxaline derivatives from various substituted o-phenylenediamines 1,2-diketones/α-hydroxy ketones using is described. The has advantage Lewis as well Bronsted acidity recyclability without significant loss in catalytic activity. key advantages present method are high yields, short reaction times, solvent-free condition, easy workup, ability to tolerate a variety functional groups, which give economical ecological rewards.
