and 2,3-dichloro-1,4-naphthoquinone initiates the formation of benzo[e][1,3,4]oxadiazine and benzo- as well as naphthoxadiazepine derivatives. On the other hand, substituted hydrazides attack 1,4-naphthoquinone-2,3-dicarbonitrile to form benzo[f]indazole-4,9-dione derivatives. A rationale for the conversions observed is presented. J. Heterocyclic Chem., 2010.
取代的酰肼对C-2,C-3的亲核攻击 2,3,5,6-四氯-1,4-苯醌和2,3-二氯-1,4-萘醌可引发苯并[e] [1,3,4]恶二嗪和苯并-以及萘恶二氮杂卓衍生物的形成。另一方面,取代的酰肼会进攻1,4-萘醌-2,3-二甲腈形成苯并[f]吲唑-4,9-二酮衍生物。提供了观察到的转换的原理。J.杂环化学.2010。
