Answer:

A simple, highly efficient and green procedure for the condensation of aryl and alkyl 1, 2-diamines with 1,2-diketones or alphahydroxyketones in the presence of different catalyst, method and solvent is described. Using this method, quinoxaline derivatives as biologically interesting compounds are produced in high to excellent yields and short reaction times. Present synthesis complies with principle of Green chemistry. As part of current studies, we here in report efficient practical technique of grinding, reflux, stirring. The overall progress of the reaction was monitored by TLC and characterized by IR and NMR. These methods are more convenient and reactions can be carried out in higher yield, shorter reaction time and milder conditions, without generation of pollution and safer to analyst. The synthesized 2, 3-diphenyle quinoxaline was confirmed by physical constant and spectroscopic studies. Low cost and maximum efficiency are some advantages of this synthesis. From these features present methods can be correlated for safer and efficient synthesis of other products.
