gem-Dinitromethyl-Functionalized 5-Amino-1,3,4-oxadiazolate Derivatives: Alternate Route, Characterization, and Property Analysis.

A new, safer, and more cost-effective methodology to synthesize salts based on gem-dinitromethyl-functionalized 5-amino-1,3,4-oxadiazolate is given. Cyclization, deprotection, nitration, and neutralization reactions were conducted to obtain products in high yield. All compounds were fully characterized by NMR and IR spectroscopy, elemental analysis, and differential scanning calorimetry. Crystal structure analysis, property tests, and theoretical calculations confirm good detonation performance and high mechanical stabilities of the salts.
