This combined experimental and theoretical study details the vicarious nucleophilic substitution by amination of 5,7‐dinitrobenzotriazol (1) and 4,6‐dinitrobenzotriazole‐3‐ium‐1‐oxide (4) with trimethylhydrazinium iodide to afford the new corresponding one‐ and two‐time aminated compounds and investigations of its mechanism by EPR spectroscopy. The preferred position for the first amination is computed
结合实验和理论研究,详细说明了将5,7-二硝基苯并三唑(1)和4,6-二硝基苯并三唑-3-氧化1(4)胺化,用碘代三甲基碘化铵来提供新的相应的一二次胺化的化合物,并通过EPR光谱对其机理进行了研究。第一次胺化反应的首选位置由自旋密度总体计算得出,并通过X射线晶体学验证。4 H的两性离子结构在溶液中通过1 H NMR光谱研究,在固态时通过X射线衍射研究。此外,1的晶体结构被表达。关于敏感性和性能,研究了胺化产物以及原料1和4的能量行为。
