1,4-Naphthoquinone derivatives reacted with N,N-disubstituted hydrazones to give C adducts, whereas N-monoalkylhydrazones yielded N adducts which underwent ring closure to benzindazole-4,9-diones. Michael addition with methoxycarbonylbenzoquinone led to open chain mono- and disubstituted N adducts or phthalazin-1-one derivatives, depending on the hydrazone. N Adducts obtained from dimethylbenzoquinone
1,4-萘醌衍生物与N,N-二取代的azo唑反应生成C加合物,而N-单烷基azo生成N个加合物,其闭环成为苯并吲唑-4,9-二酮。取决于addition,迈克尔与甲氧基羰基苯醌的加成反应会生成开链的单取代和二取代的N加合物或酞菁-1-酮衍生物。从二甲基苯醌中获得的N加合物,通过杂Diels-Alder反应环化成苯并恶二嗪。
