Abstract

Energetic materials containing a pyrazolotriazine oxide skeleton have the potential for high performance. However, research on the pyrazolotriazine oxide skeleton is very limited due to the inherent ring system instability and limited synthetic approaches. In this paper, APTO and OPTO with a combination of high-nitrogen tetrazole and a promising azido-pyrazolotriazine oxide skeleton have been synthesized. Of these, OPTO and its energetic salts exhibit excellent detonation properties (D_v > 8220 m s^–1; P > 26.50 GPa). Surprisingly, APTO exhibits a detonation performance (D_v = 8913 m s^–1; P = 32.43 GPa) comparable to that of RDX.

四氮唑和4-叠氮多吡唑三嗪氧化物的组合：高氮、能量和安全性的平衡

含有吡唑三嗪氧化物骨架的高能材料具有高性能的潜力。然而，由于环系统固有的不稳定性和有限的合成方法，对吡唑三嗪氧化物骨架的研究非常有限。本文合成了 APTO 和 OPTO，它们结合了高氮四氮唑和前景看好的叠氮吡唑三嗪氧化物骨架。其中，OPTO 及其高能盐表现出优异的引爆性能（Dv > 8220 m s-1; P > 26.50 GPa）。令人惊讶的是，APTO 的起爆性能（Dv = 8913 m s-1；P = 32.43 GPa）与 RDX 相当。

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.
