New compounds of cyclic-azodioxides have been prepared by oxidation of the corresponding diamines with sodium tungstate and hydrogen peroxide in a mixed ethanol/water solvent. Spectroscopic techniques, including IR, UV, 1H NMR, and 13C NMR, and CHN analysis were used to identify the products. In solution, the azodioxides were found to be in equilibrium with the corresponding dinitroso compounds. The IR values of the synthesised compounds are in agreement with the theoretical IR spectra.
