amino azole of N-NH2 was verified by the X-ray crystal structure of key intermediates. In addition, four energetic compounds 4aa, 4ba, 4ac, and 4ad containing N6 and N7 structures possess acceptable decomposition temperatures (150.1–201.6 °C) and moderate calculated detonation performances (6850–7727 m/s). Among them, 4aa (N6 structure) and 4ad (N7 structure) could be used as the melt-cast explosive
从甲苯磺酰hydr和N-氨基(N -NH 2)唑代替C-氨基胺衍生物开发了一种用于双(1,2,3-三唑)形成反应的简便,通用的合成策略。以中等或高收率合成了含有自行车链状六氮链(N 6)的新型高能化合物和N 7中性化合物的第一个实例。通过关键中间体的X射线晶体结构验证了基于N -NH 2氨基唑的双(1,2,3-三唑)形成反应的可能机理。此外,四种高能化合物4aa,4ba,4ac和4ad含有N 6和N 7结构的分解温度(150.1–201.6°C)和计算的爆轰性能(6850–7727 m / s)是可以接受的。其中,可以将4aa(N 6结构)和4ad(N 7结构)分别用作熔铸炸药候选物和气体发生剂候选物。这种类型的氮-氮键形成为发现含有链状多个氮原子(尤其是奇数氮化合物)的新型高氮高能化合物开辟了新方法。
