The oxidative demethylation of polymethoxynaphthalenes such as 1,4-di, 1,4,5-tri, 1,4,5,8-tetra, and 1,2,4,5,8-pentamethoxynaphthalenes with silver-catalyzed ammonium peroxodisulfate gave the corresponding 1,4-naphthoquinones in good yield under mild reaction conditions.
在银催化的过二硫酸铵作用下,1,4-二、1,4,5-三、1,4,5,8-四和 1,2,4,5,8-五甲氧基萘等多甲氧基萘在温和的反应条件下发生氧化脱甲基反应,得到了相应的 1,4-萘醌,收率很高。
