摘　　要：利用对二甲氨基苯胺盐酸盐和亚硝酸钠反应得到对二甲氨基苯基重氮盐,低温下与叠氮化钠反应制得1-(对二甲氨基苯基)五唑。采用低温核磁共振氢谱(1H NMR)对目标化合物进行了表征,利用程序升温核磁共振分析了温度变化时目标化合物在溶剂体系中的稳定性,并对五唑衍生物的生成及分解机理进行了讨论。The 1-（p-dimethylaminophenyl）pentazole was synthesized at low temperature with sodium azide and p-dimethyldiazonium which was synthesized by coupling sodium nitrite with p-dimethylphenylenediamine dihydrochloride in aqueous media. Its structure was characterized by ^1H NMR at-20℃. The stability of 1-（p-dimethylaminophenyl）pentazole in solvent at different temperatures was further analyzed by ^1H NMR with a dynamic heating process from - 50 ℃ to 25 ℃. It is concluded that the stability is less stable in solvent, and it decomposes almost at 25 ℃ for several minutes. According to the results of the ^1H NMR analysis, the reaction mechanism of decomposition and synthesis of arylpentazole, which was put forward by Bulter et al, are eonfirmed.
