Abstract:

改进3-(N-2,4,6-三硝基苯基)-氨基-4-硝基呋咱、3-氨基-4-(1H-5-四唑基)呋咱、3-硝基-4-(1H-5-四唑基)呋咱、3,3′-(1H-5-四唑基)-4,4′-偶氮呋咱及3-氨基-4-(4-氰基-5-氨基-1-1,2,3-三唑基)呋咱的合成方法,反应条件相对温和,产率相应提高:3-氨基-4-硝基呋咱与2,4,6-三硝基氯苯(苦基氯)反应以36.1%的收率制得3-(N-2,4,6-三硝基苯基)-氨基-4-硝基呋咱;3-氨基-4-氰基呋咱和叠氮基成环得到3-氨基-4-(1H-5-四唑基)呋咱,产率90.9%;以高锰酸钾为氧化剂氧化3-氨基-4-(1H-5-四唑基)呋咱合成出86.8%的3,3′-(1H-5-四唑基)-4,4′-偶氮呋咱,以30%的双氧水、钨酸钠及甲磺酸为氧化体系则得到75.6%的3-硝基-4-(1H-5-四唑基)呋咱;3-氨基-4-叠氮基呋咱与丙二腈作用制得3-氨基-4-(4-氰基-5-氨基-1-1,2,3-三唑基)呋咱,产率为91.8%;采用核磁、红外、质谱等分析手段对所合成化合物进行结构表征。
