Quinoxalines are nitrogenous compounds that are widely used in various industries like paint, pharmaceutical and medicine. By using of this synthetic method of these compounds based on condensation of Aryl-1,2-di amine with 1,2-di carbonyl in the Acidic condition, some new compounds was obtained from Quinoxaline family that for the first time some new catalysts was used for increasing of efficiency and reducing of process time. Used catalyst was CrCl2.6H2O compound that preparation of these catalysts is economically, cost-effective and saves time. All mechanisms were done in ethanol solvent at room temperature. However, all results suggest a mild and heterogeneous nature of these mechanisms, shorter time of reaction and higher yield.
