Although azo-bis-formamidine dinitrate cannot be converted to the dinitro derivative directly it can be chlorinated in water to azo-bis-chloroformamidine and thence to azo-bis-nitroformamidine in nitric acid and acetic anhydride. When the latter substance is treated with 2-methylpentadiene-1,3 an alkali-soluble compound is obtained which is specified as 1-imino-3-nitrimino-4,6(or 5,7)-dimethyl-2,8
尽管偶氮双甲脒二硝酸盐不能直接转化为二硝基衍生物,但它可以在水中氯化成偶氮双氯甲脒,然后在硝酸和乙酸酐中氯化成偶氮双硝基甲脒。当后一种物质用 2-methylpentadiene-1,3 处理时,得到一种碱溶性化合物,它被指定为 1-imino-3-nitrimino-4,6(or 5,7)-dimethyl-2,8,9 -triaza-4,6,8,9-tetrahydroindandione-1,3。该反应的特征表明偶氮双硝基甲脒以亚氨基互变异构体形式存在。与 2-methylpentadiene-1,3 的 Diels-Alder 反应在类似的反应中有其对应物,其中偶氮-双甲脒转化为 1,3-diimino-4,6-二甲基-2,8,9-triaza-4 ,6,8,9-四氢茚二酮-1,3mononitrate和硝酸铵。
