Gem-dinitro compounds in organic synthesis. 4. Use of the condensation product of glyoxal and dinitromethane in the synthesis of nitro-1,2,3-triazoles
摘要:
The condensation of dinitromethane with glyoxal has been investigated and it has been demonstrated that 1,1,4,4-tetranitro-2,3-butandiol, alpha-hydroxy-beta,beta-dinitropropionic acid or their mixture may be formed. Interaction of 1,1,4,4-tetranitro-2,3-butandiol or 1,4-dibromo-1,1,4,4-tetranitro-2,3-butanediol diacetates with sodium azide leads to bis(5-nitro-1,2,3-triazol-4-yl) via intermediate 1, 1,4,4-tetranitro-1,3-butadiene.

sequence of nitration, fluorination, and difluoroamination reactions, providing the respective 2,2'-bis(trinitromethyl)-, 2,2'-bis(dinitro(fluoro)methyl)-, and 2,2'-bis[(N,N-difluoroamino)dinitromethyl] derivatives. The structures of all six products were studied by X-ray structural analysis; their crystal lattices were found to have high density (from 1.831 to 1.959 g/cm3 at 295 K). According to DTA

General methods have been worked out for the alkylation of nitroazoles with bromoacetone, bromoacetophenone, and diazoacetone in homogeneous media and by phase-transfer catalysis. The structures of the N-acetonylazoles were established by C-13, N-15, and N-14 high-resolution NMR spectroscopy.

Using a variety of functionalization strategies, derivatives of 4, 4′‐bis(5‐nitro‐1,2,3‐2H‐triazole) were designed, synthesized, and characterized. The isomers were separated, their structures were confirmed with single‐crystal X‐ray analysis, and their properties were determined by differential scanning calorimetry, density, impact sensitivity, heat of formation, and detonation velocity and pressure
