Five easy, relatively inexpensive, and environmentally-safe aromatic oxidative iodination procedures are presented; three of them are particularly suitable for deactivated arenes. Nine deactivated arenes, four halobenzenes, benzene, toluene, and N,N-dimethylaniline were reacted upon with the following anhydrous systems: diiodine/NaIO4 or (in four cases) NaIO3/acetic anhydride/glacial acetic acid, acidified with varying amounts of concd (98%) sulfuric acid; the following workups are explained. The aromatic oxidative iodination reactions proceeded mostly at room temperature and within 1—8 h to give fifteen mono- and two diiodinated purified products (sometimes obtained in 2—3 different ways) in 51—95% yields.
介绍了五种简单、相对廉价且环境安全的芳香族氧化碘化方法,其中三种特别适用于非活化芳烃。对九种非活化芳烃、四种卤代苯、苯、甲苯和N,N-二甲基苯胺进行了反应,采用了以下无水体系:二碘/NaIO4或(在四种情况下)NaIO3/乙酸酐/冰醋酸,酸化时使用了不同量的浓(98%)硫酸;并解释了相应的后处理步骤。芳香族氧化碘化反应大多在室温下进行,并在1—8小时内完成,得到了十五种单碘化物和两种双碘化物纯化产物(有时通过两三种不同的方式获得),产率为51—95%。
