Glycerin and CeCl3 · 7H2O: A New and Efficient Recyclable Reaction Medium for the Synthesis of Quinoxalines
摘要:
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.
