compounds. Using this strategy, 5-(dinitromethyl)-3-(trinitromethyl)-1,2,4-triazole (6) and its ionic derivatives (7–12) were designed, prepared and thoroughly characterized. This family of new energetic materials exhibits excellent densities, good detonation performances and moderate mechanical sensitivities. Interestingly, as supported by the X-ray structure of energetic salt 8, the amine-based fused
制备宝石-三硝基化合物的一种极好的方法是基于具有相邻羰基结构的活性亚甲基部分的破坏性硝化作用。现在描述一种替代方法,其中利用氧化硝化来合成宝石-三硝基化合物。使用这种策略,设计,制备了5-(二硝基甲基)-3-(三硝基甲基)-1,2,4-三唑(6)及其离子衍生物(7-12),并对其进行了全面表征。该系列新的高能材料具有出色的密度,良好的爆震性能和中等的机械敏感性。有趣的是,在高能盐8的X射线结构的支持下,基于胺的稠合环阳离子诱导了面对面的π-π排列,从而降低了整个分子的敏感性,并促进了类似的稠合环离子稳定剂在聚硝基唑阴离子中的进一步应用。这些结果开启了有关高能材料领域的宝石-三硝基化合物的新篇章。
