Abstract

Although dinitroimino compounds I–V exhibit excellent detonation performance, their poor stability (T_d < 200 °C) limits their applications. In this study, a novel tricyclic fused skeleton was obtained using a rare one-pot strategy involving a condensation, a cyclization, and an intramolecular cyclization. Dinitroimino derivative 5 demonstrates superior detonation performance (D_v = 9023 m s^–1, and P = 33.9 GPa) and improved stability (T_d = 235 °C) compared to those of reported dinitroimino compounds I–V and RDX (T_d = 204 °C).

具有增强稳定性的二氨基三环熔合环含能材料的一种方法

虽然二硝基亚胺化合物I-V表现出优异的爆轰性能，但其稳定性差(Td <；200°C)限制了它们的应用。在这项研究中，利用一种罕见的一锅策略，包括缩合，环化和分子内环化，获得了一个新的三环融合骨架。与已报道的二硝基亚胺化合物I-V和RDX （Td = 204°C）相比，二硝基亚胺衍生物5具有更好的爆轰性能（Dv = 9023 m s-1, P = 33.9 GPa）和更高的稳定性（Td = 235℃）。

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.
