Abstract

In this study, the preparation of quinoxaline derivatives using α-diketones, 1,2-phenylene diamines in the presence of H2SO4/SiO2 catalyst in ethylene glycol and at room temperature is reported. The advantages of this method are high yields of the products, utilizing of reusable catalyst, easy separation and mild reaction conditions. Also, reusability of the catalyst was investigated and found that catalytic activity of the catalyst did not decreased after 4th times.
