A series of tetracyclic furazan-triazole compounds have been synthesized and fully characterized. The predicted detonation performance and tested mechanical sensitivities showed their high-energy performance and insensitive features. Quantum chemical calculations and crystal structure analysis were applied to study the intrinsic structure-property relationship among these compounds. In addition, the detonation test shows their promising potential as secondary explosives.

Paragraph 0038-0041; 0044, (2020/07/28)
The invention provides benzimidazole bifurazan series compounds and a synthesis method thereof. The molecular structure of the compounds is represented by a formula I, wherein R1 is selected from hydrogen, halogen, trifluoromethyl, nitryl, amino, sulfo, methyl, tert-butyl, methoxyl, carboxyl, ethoxyformyl or benzoyl; R2 is selected from hydrogen or fluorine. On the basis, the invention discloses an efficient method for preparing the series of compounds. The preparation method comprises the steps: synthesizing an intermediate 4-amino-1,2,5-oxadiazole-3-methoxyamidine by taking malononitrile asa starting raw material, carrying out a reaction on the intermediate with o-phenylenediamine or a substitute thereof under a heating reflux condition by taking acetic acid as a solvent, cooling, adding water, stirring to separate out a solid after the reaction is finished, and carrying out suction filtration, washing, drying and the like to obtain a final product. According to the method, a pure product can be obtained without recrystallization, column chromatography separation and other steps, the method is simple, rapid and practical, and the yield can generally reach 80% or above.

Iminoester of 3-aminofurazan-4-carboxylic acid was synthesized for the first time. Starting with the iminoester were prepared amidrazone of 3-aminofurazan-4-carboxylic acid, 1,4-diamino-1,4-bis(3-aminofurazan-4-yl)-2,3-diaza-1,3-butadiene, 1-amino-1,4-bis(3-aminofurazan-4-yl)-4-oxo-2,3-diaza-1-butene, and 3,5-bis(3-aminofurazan-4-yl)-1H-1,2,4-triazole. The alkylation of the latter with methyl iodide gave rise to a mixture of 1- and 4-methyl-3,5-bis(3-aminofurazan-4-yl)-1,2,4-triazole containing predominantly 1-isomer.
