FSO2ONF2 (I) reacts with anions of NH-azoles (imidazoles, pyrazoles, 1,2,3-triazoles) yielding the corresponding N-fluorosulfonylazoles from which sulfonylbisazoles are obtained. N-Fluorosulfonylation occurs at nitrogen atom which is farthest from the most electron-accepting substituent. Anions of nonaromatic NH-acids (imides, primary N-nitramines) can undergo N-fluorosulfonylation, however the yield is low (<5%) and the products are significantly less stable than N-fluorosulfonylazoles. N-Fluorosulfonylation occurs as nucleophilic substitution at the sulfur atom of I.

Making use of the extended kinetic method and the alternative method for data anal., we have exptl. determined ΔH°acid (kcal/mol) for six mononitrated azole species (2-nitropyrrole = 337.0, 3-nitropyrrole = 335.8, 3-nitropyrazole = 330.5, 4-nitropyrazole = 329.5, 2-nitroimidazole = 327.4, and 4-nitroimidazole = 325.0). We report an absolute uncertainty of ±2.2 kcal/mol that arises from the uncertainties of the reference acids; the relative values are known within 0.4 kcal/mol. Combining these exptl. ΔH°acid values with ΔS°acid values calculated at the B3LYP/aug-cc-pVTZ level of theory, we report ΔG°acid (kcal/mol) for the nitroazoles (2-nitropyrrole = 329.4, 3-nitropyrrole = 328.4, 3-nitropyrazole = 323.1, 4-nitropyrazole = 322.0, 2-nitroimidazole = 319.7, and 4-nitroimidazole = 317.6); the absolute uncertainties are ±2.4 kcal/mol. In addition to the exptl. studies, we have computationally investigated the gas-phase acidities and electron affinities of the azoles in this work, as well as higher-order aza- and dinitro-substituted azoles. We discuss trends in the stabilities of the deprotonated azoles based on aza substitution and nitro group placement. 4-Nitroimidazole has already found use as the anionic component in ionic liquids, and we propose that the addnl. nitrated azolate ions are potential candidates for the anionic component of ionic liquids

Gamezo, V. N. published the artcileTheoretical analysis of the effects of nitration of the explosive properties of triazoles: 4-nitro-2H-1,2,3-triazole and 4,5-dinitro-2H-1,2,3-triazole, Quality Control of 84406-63-3, the publication is Journal of Molecular Structure: THEOCHEM (1995), 337(2), 189-97, database is CAplus.

At the mol. level, the ground-state intrinsic energies of the C-NO2 and N-N bonds and the excited-state bond polarities of the 4-nitro- and 4,5-dinitro-2H-1,2,3-triazoles were compared using their theor. optimized geometries. Their enthalpies of formation were calculated using a modified Xα approach; finally, their explosive characteristics were studied at the macroscopic level with the help of the thermodn. code of Kondrikov-Sumin. With respect to the planar mononitro derivative, the second nitration provokes: (1) a torsion of ∼30° of the two nitro groups, (2) a significantly decreased C-N bond dissociation energy, by ∼9 kcal/mol, together with a weakening of the N-N bonds, thus reducing thermal stability, (3) an increase of C-NO2 and N-N bond polarities in the electronically excited states, correlated with a decreased shock sensitivity, and (4) an increase in gas-phase enthalpy of formation, from -25 kcal/mol (or -51 kcal/mol, estimated for the condensed phase) for the mononitro derivative to +65 kcal/mol (e.g., +50 kcal/mol) for the dinitro compound Using these enthalpy results and a Kondrikov-Sumin-like equation of state, one can describe the ideal velocity of detonation DCJ as a function of the d. ρ0 by DCJ = 0.337 + 3.86ρ0 ,and DCJ = 2.246 + 3.61ρ0 for the mononitro and dinitro derivatives, resp., thus giving the corresponding detonation velocities of 6.5 and 8.0 km/s for an assumed d. of 1.6 g/m3.
