2,3-Disubstituted quinoxalines were synthesized via condensation of α-diketones and 1,2-phenylenediamines. Nano-BF3·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
