摘要：

A facile procedure for the synthesis, of quinoxalines. is being reported starting from benzil and 1,2-diaminobenzene. The reactions were carried out catalyst-free, solvent-free and under microwave irradiation conditions in high yield (84-98%) with short time (3-6 min) and environmental benign, as well as convenient operation. The structures of all the compounds have been confirmed on the basis of their IR, H-1 NMR, and/or C-13 NMR, mass spectral data.
