In this research, some condensation reactions have been carried out between 2-methylquinoxaline-1,4- dioxid derivatives and terephthaldehyde. The structures of all products have been suggested depending on IR, and NMR spectroscopic methods. Suitable mechanisms have been suggested for their formation. The Quinoxalines derivatives have been prepared from 2- nitroaniline derivatives via Beirut reaction. The products were sparingly soluble in all available solvents. Sulfonation reactions have been tried of products but without reasonable success

Keywords : 2-methylquinoxaline-1,4-dioxid; terephthaldehyde; 2-nitroaniline derivatives; Beirut reaction; condensation reaction.
