Hydrazoic acid in the Mannich reaction
Gafarov
, p. 2169 - 2172 (2009)
The possibility of the three-component condensation of hydrazoic acid and formaldehyde with primary or secondary amines, as well as with trialkylhydrazines, leading to the corresponding N-azidomethyl derivatives of amines and hydrazides was established.

Numerous efforts to substitute TNT as the melt-cast matrix in explosive charges are ongoing due to its low performance and security issues. In this study the syntheses and full structural as well as spectroscopic characterizations of 2-nitrazapropyl substituted polynitroazoles, as potential melt-cast explosives, are presented. This straightforward method of derivatizing the heterocyclic N-H function by introducing a further energetic group improved the stability and energetic properties of the products. X-ray crystallographic measurements were performed for all compounds and afforded insights into structural characteristics such as strong intermolecular interactions. All compounds were characterized in terms of their sensitivities towards impact, friction and electrostatic discharge, and their thermal stabilities. The energetic properties were calculated with the EXPLO5 6.02 program.

The alkylation of 2-nitro-2-azapropyl chloride (2) and deprotonated 5-amino-1H-tetrazole (3), 1H-tetrazole (4), 5-nitriminol,4H-tetrazole (5), 1-methyl-5-nitrimino-4H-tetrazole (6) and 2methyl-5-nitraminotetrazole (7) afforded the products 1.-(2-nitro-2-azapropyl)-5-aminotetrazole (8), 1-(2-nitro-2-azapropyl)-5H-tetrazole (9), 1-(2-nitro-2-azapropyl)-5- nitriminotetrazole.H2O (10a), 1-(2-nitro-2azapropyl)-S- nitriminotetrazole-EtOH (10b) 1,5-bis(2-nitro-2-azapropyl)-5-nitraminotetrazole (11), 1.-methyl-5-(2-nitro-2-azapropyl)-5-nitraminotetrazole (12), 1-methyl-4-(2-nitro-2-azapropyl)-5-nitraminotetrazole (13), 1-methyl-5-(2-nitro- 2-azapropyl)-5-aminotetrazole (14) and 2-methyl-5-(2-nitro-2-azapropyl)-5- nitraminotetrazole (15). In addition, the reaction of potassium 1-methyl-5-nitriminotetrazolate with dimethyl sulfate was investigated yielding 1,4-dimethyl-5-nitriminotetrazole (16). All products (8-16) were determined by low tempera ture single X-ray diffraction. A comprehensive characterization and description of the chemical properties (IR, Raman, and multinuclear ( 1H, 13C and 15N) NMR spectroscopy, mass spectrometry, elemental analysis and differential scanning calorimetry) is given. The heats of formation were calculated by heats of combustion measured using bomb calorimetry. With these values and the X-ray densities, several, detonation parameters (e.g. detonation pressure, detonation, velocity, heat of explosion) were computed by the EXPLO5 software. In addition, the sensitivities towards impact, friction and electrical discharge were determined.
