Abstract:
A direct synthetic route to an assembly of new energetic materials composed of two 1,2,5-oxadiazole 2-oxide (furoxan) rings connected via an azoxy linker and coupled with a 4-nitramino-3,5-dinitrophenyl scaffold was realized. Due to an advanced installation of azoxy and nitramino moieties, synthesized materials showed good densities (1.65-1.74 g cm-3) and an increased oxygen balance. Advantageously, all prepared energetic substances demonstrated good detonation velocities (7.3-7.8 km s-1) and retained acceptable sensitivity to impact, thus elucidating new directions in the construction of balanced high-energy materials.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...

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...
