    Notes: A study of the coupling reactions of the aminoquinoxalines 1, 2a and 2c was undertaken to characterise the orientation in the homocyclic ring in the quinoxaline molecule.The aminoquinoxalines investigated were diazotised with nitrous acid and the resulting diazonium salts coupled with alkaline β-naphthol to give the azo dyes 3 and 4.Several new intermediates and dyestuffs containing the quinoxaline moiety were prepared. The electronic spectra of these new azo dyes were discussed.
