A convenient procedure for the synthesis of N-nitroaminofurazans by nitration of primary 3-amino-4-R-furazans (R = Me, NO2, phenyl-, methyl-NNO-azoxy-, tert-butyl-NNO-azoxy-, tert-butyldiazenyl-, etc.) with 66–77% aqueous nitric acid was developed. Depending on the concentration of HNO3, the reaction is carried out at a temperature from 18 to 55 °C, the yield of the products is 80–99%. 3-Nitramino-4-phenylfurazan with unsubstituted benzene ring was obtained by nitration of 3-amino-4-phenylfurazan.

A series of bridged bisnitramide energetic compounds was designed and synthesized based on amino/nitro-functionalized furazans with methyl-NNO-azoxy, 1,2,4-oxadiazole and 3-hydrazino(imino)methyl side-chain groups. For comparison, 4-(methyl-azoxy)-3-nitraminofurazan as a direct nitration product and the corresponding ammonium salt were also prepared. All new compounds were thoroughly characterized
