摘要：
A series of quinoxaline derivatives were efficiently synthesized in excellent yields by the reaction of 1,2-diamines and 1,2-diketones with grinding catalyzed by p-toluenesulfonic acid under solvent-free conditions at room temperature. Compared with the classical synthetic method, this new method has the advantages of convenient manipulation and environmental friendliness.
