主　　题：Quinoxalins Citric acid o-Phenylenediamines 1 2-Dicarbonyl compounds Green catalyst 

摘      要：The condensation of o-phenylenediamines with 1,2-dicarbonyl compounds in the presence of citric acid afforded the corresponding quinoxaline derivatives in higher yields at room temperature in ethanol,and most of the reactions were completed in less than 1 min.
