Studies on Condensed Heterocyclic Compounds (XV)──Synthesis of 3-(1H-benzotriazole-1-methylene)-1,2,4- triazolo(3,4-b)-1,3,4-thiadiazoles
【摘要】 研究了3-(1H-苯并三唑-1-亚甲基)-4-氨基-5-巯基-1,2,4-三唑与取代苯甲酸在三氯氧磷催化下的反应,制得10种新的3-(1H-苯并三唑-1-亚甲基)-1,2,4.三唑并[3,4-b]-1,3,4-噻二唑,通过元素分析、IR、 ̄1NMR和MS确证了它们的结构并讨论了其波谱性质。
【Abstract】 By the condensation of 3-(1H-benzotriazole-1-methylene)-4-amino-5-mercapto-l,2,4-triazole with substituted benzoic acids in the presence of phosphorus oxychloride,ten novel 3-(1H-benzotriazoles)were obtained. Their structures were determined by elementary analysis, IR,1H NMR and MS. Their spectral properties were also discussed.
