Abstract

Abstract To achieve a balance between detonation performance and thermal stability, a synergistic strategy based on ortho-nitroamino groups and a hydrazine bridge was adopted in this work. Using this approach, compound 2 (6,6′-(hydrazine-1,2-diyl)bis(3,5-dinitropyridine-2,4-diamine)) and its perchlorate (3) and nitrate (4) salts were successfully synthesized via a one-step method in high yield. Notably, compound 3 shows a high thermal decomposition temperature (Td = 316 °C) which is comparable to that of HNS (Td = 318 °C), and its energy performance (Dv = 9135 m·s–1, Pe = 37.9 GPa) approaches that of HMX (Dv = 9144 m·s–1, P = 39.2 GPa). These results demonstrate the potential of compound 3 as a heat-resistant and insensitive explosive for practical applications. Furthermore, they highlight that the synergistic effect of hydrazine bridging and ortho-nitroamino groups holds promise for achieving a balance between high energy and low sensitivity.

基于邻硝基氨基和联氨桥的高能低敏能材料协同构建

摘要为了在爆轰性能和热稳定性之间取得平衡，本文采用了基于邻硝基和联氨桥的协同策略。利用该方法，一步合成了化合物2(6,6′-（肼-1,2-二基）二（3,5-二硝基吡啶-2,4-二胺）及其高氯酸盐(3)和硝酸盐(4)盐，收率高。化合物3的热分解温度（Td = 316℃）与HNS （Td = 318℃）相当，其能量性能（Dv = 9135 m·s-1, Pe = 37.9 GPa）接近HMX （Dv = 9144 m·s-1, P = 39.2 GPa）。这些结果证明了化合物3作为一种耐热不敏感炸药具有实际应用的潜力。此外，他们强调肼桥接和邻硝基氨基的协同效应有望实现高能量和低灵敏度之间的平衡。

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
