An efficient and environmentally benign process for the synthesis of quinoxalines has been developed using glycerine-cerium chloride as a reaction medium. This method is applicable to a variety of diketones and 1,2-phenylenediamines to afford the corresponding quinoxaline derivatives in excellent yields. The reaction medium was recovered and reused for further reactions without any problem.

A simple and efficient method for the synthesis of quinoxalines derivatives has been developed. All the reactions were carried out in presence of niobium (V) chloride at acetonitrile reflux conditions. The method is applicable to a variety of diketones and 1, 2-phenylenediamines to afford the corresponding derivatives in excellent yields.
