摘要：

2,3-Disubstituted quinoxalines were synthesized via condensation of alpha-diketones and 1,2-phenylenediamines. Nano-BF3 center dot SiO2 as a "green" and reusable solid acid was used as the catalyst for the synthesis of quinoxalines. The reaction was carried out at room temperature under sonication with high to excellent yields.
