The nucleophilic displacement of two nitro groups in 3,4-bis(3-nitrofurazan-4-yl)furoxan with ammonia, primary aliphatic amines and hydrazine leads to formation of a novel heterocyclic system, 7H-tris[1,2,5]oxadiazolo[3,4-b:3′,4′-d:3″,4″-f]azepine. The reaction of compound 1 with secondary aliphatic amines proceeds in a typical way for nitrofurazans when the nitro-group in the starting compound is
3,4-双(3-硝基呋喃唑-4-基)呋喃喃中的两个硝基被氨,伯脂肪族胺和肼的亲核取代导致形成新型杂环系统7H-tris [1,2,5] oxadiazolo [3,4-b:3',4'-d:3″,4″ -f]氮杂。当起始化合物中的硝基被RR'N-基团取代时,化合物1与仲脂肪族胺的反应以典型的方式进行硝基呋喃丹的反应。
