Baryshnikov, A. T. published the artcileGem-dinitro compounds in organic synthesis. 3. Syntheses of 4-nitro-1,2,3-triazoles based on gem-dinitroethylenes, Formula: C2H2N4O2, the publication is Izvestiya Akademi Nauk, Seriya Khimicheskaya (1992), 958-66, database is CAplus.
Several chemoselective approaches to the title triazoles I (R = H, Me, Bu) are developed from NaN3 and gem-dinitroethylenes, readily available from the transformation products of dinitroacetic acid esters, N-(β,β-dinitroethyl)-N,N-dialkylamines, 2,2-dinitroethanol acetate, mixtures, of dinitroacetic acid esters with aliphatic aldehydes, or 1,1,1-trinitroalkanes. Hitherto unavailable 4-nitro-5-amino- and 4,5-dinitro-1,2,3-triazoles were prepared via successive transformations of the Me group in 4-nitro-5-methyltriazole. Nitration of 4-nitro-1,2,3-triazole with nitronium tetrafluoroborate or acetyl nitrate gave the novel 2,4-dinitro-1,2,3-triazole.
Izvestiya Akademi Nauk, Seriya Khimicheskaya published new progress about 14544-45-7. 14544-45-7 belongs to triazoles, auxiliary class Triazoles, name is 5-Nitro-1H-1,2,3-triazole, and the molecular formula is C2H2N4O2, Formula: C2H2N4O2.
