Synthesis of 2,3-diarylquinoxaline via the condensation of 1,2-diarylethanedione and 1,2-phenylenediamine was carried out in excellent yields (90%~97%) in acetic acid at room temperature within 1~10 min. This method provides several advantages such as short reaction time, high yields, simple operation and mild conditions.
