    Abstract:

    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 confirmed.
