l}-NNO-azoxy)furazan (5a). This compound contains a new explosophore (3-nitro-1H-1,2,4-triazol-1-yl)-NNO-azoxy moiety. The oxidation of the amino group in aminofurazan 5a with an excess N2O5 of resulted in the corresponding nitro derivative 5b. Aminofurazan 5a reacted with DBI to give the corresponding azo compound 5c. Compounds 5a,c may be of interest as energetic substances due to the combination
