The nitrogen-rich compounds and intermediates with structure of monocyclic, bicyclic, and fused rings based on 1,2,3-triazole were synthesized and prepared by using a promising precursor named 4,5-dicyano-1,2,3-triazole, which was obtained by the cyclization reaction of diaminomaleonitrile. Their structure and configurational integrity were assessed by Fourier transform-infrared spectroscopy (FT-IR)
合成并制备了基于1,2,3-三唑的具有单环、双环和稠环结构的富氮化合物和中间体,该前驱体名为4,5-二氰基-1,2,3-三唑,由二氨基马来腈环化反应得到。它们的结构和构型完整性通过傅里叶变换红外光谱 (FT-IR)、质谱 (MS) 和元素分析 (EA) 进行评估。此外,通过 X 射线单晶衍射进一步证实了 14 种化合物。同时,选定的四种化合物(3 ·H 2 O、6 ·H 2 O、10 ·H 2 O 和16) 包括热稳定性、爆轰参数和灵敏度。所有这些化合物都可以被认为是构建更丰富的基于1,2,3-三唑的中性高能分子、盐和复杂的化合物,这些都需要在未来的高能材料领域继续研究。
