isolated. The compounds were characterised by multinuclear NMR spectroscopy, IR and Raman spectroscopy, elemental analysis as well as mass spectrometry. X‐ray diffraction studies were performed and the crystal structures for the 5,5'‐dimethyl and 5,5'‐(fluorodinitromethyl) derivatives are reported. The energetic 5,5'‐(fluorodinitromethyl) and 5,5'‐(trinitromethyl) compounds do not contain any hydrogen
在这里,我们报告了制备两个无氢原子的3,3'-bi(1,2,4-恶二唑)衍生物的方法。5,5'-双(二硝基甲烷)-3,3'-bi(1, 2,4-恶二唑)。对于我们先前报道的类似物5,5'-双(三硝基甲基)-3,3'-bi(1,2,4-恶二唑),从新的3,3'-bi(1,2,4)开始的新合成途径(恶二唑基)-5,5'-二乙酸被开发出来。在此过程中,还分离了迄今未知的5,5'-二甲基-3,3'-bi(1,2,4-恶二唑)。通过多核NMR光谱,IR和拉曼光谱,元素分析以及质谱对化合物进行表征。进行了X射线衍射研究,并报告了5,5'-二甲基和5,5'-(氟代二硝基甲基)衍生物的晶体结构。精力充沛的5,5' -(氟二硝基甲基)和5,5'-(三硝基甲基)化合物不包含任何氢原子,并且显示出显着的高密度。此外,通过差示扫描量热法(DSC)以及标准化的冲击和摩擦测试确定了热稳定性和敏感性。通过基于CBS-4
