This work outlines the synthesis of 5-nitromethyl-1H-tetrazole (NMT) and its use in the synthesis of various high-nitrogen materials. It can be reacted with the diazonium salt of 5-aminotetrazole to produce a tetrazene-like energetic hydrazone material. Like tetrazene, N-(1H-tetrazole-5-yl)nitro(1H-tetrazole-5-yl)hydrazone hydrate (TNTH) exhibits high sensitivity to mechanical stimuli while being more thermally stable: 209 °C decomposition and 16% mass loss at 90 °C for 10,000 min versus 150 °C decomposition and 36% mass loss for tetrazene. NMT can also be used as an activated methylene carbon source in the synthesis of 2,3,5-trisubstituted tetrazolium salts. 2,3,5-Tri(1H-tetrazole-5-yl)-2H-tetrazole as an internal zwitterion (TTT) was synthesized and found to be deliquescent, and its salts were extremely unstable.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...

As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
