basic framework resulted in various energetic compounds having mono, di or tri nitro-substituted pyrazole moieties, and an amino or nitroimino-substituted tetrazole ring. All the compounds were thoroughly characterized by IR, and NMR [1H, 13C1H}, 15N] spectra, elemental analysis, and differential scanning calorimetry (DSC). Some of them were also structurally characterized with single-crystal X-ray diffraction
描述了通过高能吡唑与四唑部分通过N,N′-亚乙基桥键合来微调高能化合物的性质的新方法。各种吡唑衍生物与2-卤代乙胺反应,然后与叠氮化氰反应,导致形成具有乙烯桥连的5-氨基四唑和硝基吡唑的化合物。在该基本构架上的进一步反应产生了具有单,二或三硝基取代的吡唑部分以及氨基或硝基亚氨基取代的四唑环的各种高能化合物。所有化合物均通过IR和NMR [ 1 H,13 C 1 H},15N]光谱,元素分析和差示扫描量热法(DSC)。其中一些还通过单晶X射线衍射研究进行了结构表征。分别使用高斯03和EXPLO5 v6.01程序计算了所有高能化合物的形成热和爆轰性能。初步研究表明,通过仔细选择吡唑和四唑环上的高能基团的数量和性质,可以确实微调高能化合物的性能。
