摘　　要：以呋咱并[3,4-e]-1,2,3,4-四嗪-4,6-二氧化物(FTDO)为原料,经水解反应合成了新型富氮含能材料5H-[1,2,3]三唑并[4,5-c]呋咱(2),然后与氨气、水合肼、脒基脲盐酸盐、三氨基胍硝酸盐反应合成了[1,2,3]三唑并[4,5-c]呋咱铵盐(3)、[1,2,3]三唑并[4,5-c]呋咱肼盐(4)、[1,2,3]三唑并[4,5-c]呋咱脒基脲盐(5)和[1,2,3]三唑并[4,5-c]呋咱三氨基胍盐(6)4种新的含能衍生物,并采用红外光谱、核磁共振光谱、元素分析等进行了结构表征;探讨了水解反应的机理和条件,确定最佳条件为:80℃下反应5 h,收率为76.92%;采用DSC热分析手段研究了化合物2、4、5和6的热性能,其初始分解峰温分别为173.23,144.82,172.81,164.94℃。A novel nitrogen-rich energetic material 5H-[1,2,3]triazolo[4,5-c][1,2,5]oxdiazole（2） was prepared via hydrolytic reaction using [1,2,5]oxadiazole [3,4-e][1,2,3,4]tetrazine 4,6-di-N-oxide（FTDO） as raw material. Four new energetic derivatives, ammonium [1,2,3]triazolo [4,5-c][1,2,5]oxdiazole（3）, hydrazinium [1,2,3]triazolo[4,5-c][1,2,5]oxdiazole（4）, guanylureaium [1,2,3]triazolo[4,5-c][1,2,5]oxdiazole（5） and triaminoguanidinium [1,2,3] triazolo[4,5-c][1,2,5]oxdiazole（6） were designed and synthesized via reactions of compound 2 with ammonia gas, hydrazine hydrate, amidinothiourea hydrochloride and triaminogunidine nitrate, respectively. Their structures were characterized by IR, NMR and elemental analysis. The mechanism and conditions of hydrolytic reaction were analyzed. The optimal reaction conditions were determined as： the reaction time 5 h and reaction temperature 80 ℃ with a yield of 76.92%. The thermal properties of compounds, 2,4,5 and 6, were analyzed by DSC. Results show that their peak temperatures of initial decomposition reaction are 173.23,144.82,172.81,164.94 ℃, respectively.
