Depending on the type of nitrating agent and the reaction temperature, nitration of 3-amino-4-methylfurazan 1 gives either nitramine or the products of formal oxidation of the amino group, namely, nitroso-, nitro-, azo-, and azoxyfurazans. The methyl group of compound 1 is resistant against all the nitrating agents studied.

A new approach to the preparation of nitrofuroxans and nitrofurazans is suggested based on the diazotization of aminofuroxans and aminofurazans in aqueous organic medium at pH = 4–5 in the presence of excess NaNO2.

An efficient two‐step one‐pot protocol for the synthesis of N‐nitrated trinitroethylamino furazans in an ionicliquid has been developed involving the condensation of aminofurazans with trinitroethanol and the N‐nitration of an intermediate Mannich base. Trinitroethylnitramino derivatives have been synthesized and characterized by multinuclear NMR spectroscopy and X‐ray crystallography. A role of the

Reactions of nitrofurazans with primary and secondary amines were studied. Conditions were found which allow the efficient replacement of the nitro group with these nucleophiles. Transformations of the amidoxime fragment, which is bound to the furazan ring and contains an amino substituent, enable one to substantially expand the spectrum of polyfunctional derivatives. The structures of the amines synthesized were studied by X-ray diffraction analysis.
