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.
