A convenient preparation method was developed for 4″-nitro-3,3′:4′,3″-ter-1,2,5-oxadiazol-4-amine by substituting one nitro group of 4,4″-dinitro-3,3′:4′,3″-ter-1,2,5-oxadiazole at treating with equivalent quantity of ammonia in solvents of low polarity. In the reaction of the obtained amino-nitro derivative with N- and О- nucleophiles depending on the reaction conditions and the nucleophile nature either substitution of the nitro group occurs for the nucleophile residue to form 4″-alkoxy-, azido-, hydraznyl- or mono- and dialkylamino-[3,3′;4′,3″]-ter(1,2,5-oxadiazol)-4-ylamines, or the compound suffers an intramolecular cyclization affording 7Н-tri-1,2,5-oxadiazolo[3,4-b:3′,4′-d:3″,4″-f]azepines.

4“-硝基-3,3'：4'，3” -ter-1,2,5-恶二唑-4-胺的合成及一些化学特性

通过取代4,4''-dinitro-3的一个硝基，开发了一种简便的制备4''-nitro-3,3'：4'，3''-ter-1,2,5-恶二唑-4-胺的方法，3'：4'，3''-ter-1,2,5-恶二唑在低极性溶剂中用等量的氨水处理。在所获得的氨基硝基衍生物与N-和О-亲核试剂的反应中，取决于反应条件和亲核试剂的性质，亲核试剂残基上会发生硝基取代，形成4”-烷氧基-，叠氮基-，肼基-或单-和二烷基氨基- [3,3'; 4'，3“] -之三（1,2,5-恶二唑）-4-基胺，或该化合物经受分子内环化，得到7 Н -三-1,2- ，5-恶二唑并[3,4-b：3'，4'-d：3″，4″ -f ]氮杂。
