Abstract:
Here, azo-fused dinitramino energetic compound 5,5'-dinitramino-8,8'-azo-1,2,5-oxadiazolo[3,4-e][1,2,4]triazolo[4,3-a]pyrazine (4) and its energetic salts 5-7 have been prepared. Azo-fused dinitramino compound 4 exhibits excellent detonation performance (P = 36.13 GPa, and Dv = 9126 m s-1), which is obviously better than that of RDX (Dv = 8796 m s-1, and P = 33.60 GPa). In addition, the thermal stability of carbonyl compound 2 (Td = 325 °C) is similar to that of HNS (Td = 318 °C) and 2 exhibits better energy properties. These properties indicate that azo-dinitramino compound 4 has potential as a new secondary explosive, while carbonyl compound 2 also has potential as a new type of heat-resistant explosive.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
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...

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...
