A series of new energetic compounds based on 4,8‐dinitraminodifurazano[3, 4‐b,e]pyrazine were synthesised and fully characterized by NMR and IR spectroscopy, and elemental analysis. The structures of compounds 3‐a, 3‐c, 3‐f, and 3‐g were determined by single‐crystal X‐ray diffraction analysis. The physicochemical and energetic properties of these energetic compounds including density, thermal stability, and energetic performance (e. g., detonation velocities and detonation pressures) were investigated. The combination of nitrogen‐rich 4,8‐dihydrodifurazano[3, 4‐b,e]pyrazine framework with highly energetic nitramino moieties endowed these as‐synthesised compounds with excellent detonation performance. Among these as‐synthesised compounds, five energetic salts (3‐a, 3‐b, 3‐c, 3‐f, and 3‐g) exhibited satisfactory calculated detonation velocities (8921–9413 m s‐1), which were superior to cyclo‐1,3,5‐trimethylene‐2,4,6‐trinitamine (RDX) (8878 m s‐1). Notably, compound 3‐f exhibits an excellent calculated detonation velocity of 9166 m s‐1 and also acceptable impact and friction sensitivities (IS=8 J, FS=108 N). The prominent detonation performance with moderate sensitivities indicates that compound 3‐f has the potential to compete with traditional high explosives.

4,8-二氨基二呋喃并[3,4-b，e]吡嗪衍生的富氮盐作为潜在的高能材料的合成
合成了一系列基于4,8-二氨基二呋喃并[3,4- b，e ]吡嗪的新型高能化合物，并通过NMR和IR光谱及元素分析对其进行了全面表征。化合物3-a，3-c，3-f和3-g的结构是通过单晶X射线衍射分析确定的。研究了这些高能化合物的物理化学和高能性质，包括密度，热稳定性和高能性能（例如，爆轰速度和爆轰压力）。富氮的4,8-二氢二呋喃并[3，4- b，e具有高能硝胺基团的]吡嗪骨架使这些合成的化合物具有出色的爆炸性能。在这些合成化合物中，五种高能盐（3-a，3-b，3-c，3-f和3-g）表现出令人满意的计算爆炸速度（8921-9413 ms -1），优于环1,3,5-三亚甲基-2,4,6-三硝酸胺（RDX）（8878 ms -1）。值得注意的是，化合物3–f表现出出色的9166 ms -1爆轰速度以及可接受的冲击和摩擦敏感性（IS = 8 J，FS = 108 N）。具有中等敏感度的突出爆炸性能表明，化合物3-f具有与传统高能炸药竞争的潜力。
