5-naphthylenediol using lead(IV) oxide gives the symmetrical bisnaphthalene indigos diosindigo A and diosindigo B together with the corresponding unsymmetrical isomer. Oxidation of the first two by nitric acid gives the binaphthyldiquinones mamegakinone and biramentaceone, respectively; the third gives the unsymmetrical diquinone rotundiquinone. Similar oxidations of related naphthylenediols are described.
使用氧化铅(IV)氧化1-甲氧基-7-甲基-4,5-萘二醇和4-甲氧基-7-甲基-1,5-萘二醇的混合物,得到对称的双萘靛蓝靛蓝A和靛蓝B以及相应的不对称异构体。前两个被硝酸氧化,分别得到双萘基二醌类马格基酮和双歧ra酮;第三个给出了不对称的对苯二酚罗通二醌。描述了相关萘二醇的类似氧化。
