- Synthesis of nitro, nitroso, azo, and azido derivatives of (4-R 1-5-R2-1,2,3-triazol-1-yl)-1,2,5-oxadiazoles by oxidation and diazotization of the corresponding amines
-
Nitro-, nitroso-, and azo-1,2,5-oxadiazoles with 4-R1-5-R 2-1,2,3-triazol-1-yl substituents were synthesized by oxidation of amino-(1,2,3-triazol-1-yl)-1,2,5-oxadiazoles (aminotriazolylfurazans). Azido-1,2,5-oxadiazole was prepared b

- Nucleophilic substitution in the furazan series. Reactions of nitrofurazans with ammonia
-
The reactions of 3-nitro-4-R-furazans with ammonia were studied. The effect of the substituent R on the specific features of the nucleophilic substitution reaction observed was considered. The nitro group attached to the furazan ring can act as both the l
