Oxidation of 4-alkylfurazan-3-amines to the corresponding nitrofurazans was achieved using mixtures of hydrogen peroxide. The volatility of the products as a function of the size of substituent R, has been studied. The phase and relaxation transitions were characterized and the thermodynamic compatibility with polyester urethane was established. The melting points and melting enthalpies of alkylnitrofurazans were determined.

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.
Reactions of 3-amino-4-methylfurazan with nitrating agents
Sheremetev,Aleksandrova
, p. 1715 - 1719 (2007/10/03)
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.

, p. 1865 - 1870 (2007/10/02)
Diazotization of aminofurazans (1) and 4-aminofuroxans (2) with nitrosylsulfuric acid in a mixture of conc.H2SO4 and H3PO4 has been studied and offered as a general method for preparing furazanyl- (3) and furoxanyldiazonium (4) salts.It has been shown tha
