Nitro-, nitroso-, and azo-1,2,5-oxadiazoles with 4-R1-5-R2-1,2,3-triazol-1-yl substituents were synthesized by oxidation of amino-(1,2,3-triazol-1-yl)-1,2,5-oxadiazoles (aminotriazolylfurazans). Azido-1,2,5-oxadiazole was prepared by diazotization of amino(triazolyl)furazan followed by treatment of the diazonium salt with sodium azide. Depending on the nature of the substituents and the reagent, triazolylfurazans
硝基-、亚硝基-和偶氮-1,2,5-恶二唑具有 4-R1-5-R2-1,2,3-三唑-1-基取代基是通过氨基-(1,2,3 -triazol-1-yl)-1,2,5-恶二唑(氨基三唑基呋喃)。叠氮-1,2,5-恶二唑是通过氨基(三唑基)呋咱的重氮化然后用叠氮化钠处理重氮盐来制备的。根据取代基和试剂的性质,三唑基呋喃唑可以发生破坏,得到氨基-R-呋喃(R = NO2,N3,氨基呋咱基),氨基由三唑环形成。
