CuO2 nano oxid as an effective catalyst a for synthesis of quinoxaline derivatives at room temperature

A simple and efficient method for the quinoxaline derivatives synthesis from the condensation of aryl-1,2 diamines with dicarbonyls in thepresence of a cataly c amount CuO2 nano oxid is described. The practical and simple method led to excellent yields of the quinoxalins undermild conditions and within short times
