无有机溶剂的芳香化合物的氧气氧化碘化反应

摘要

以硝酸铁作为催化剂，分子氧O2作为氧化剂，在回流温度下，熔融态的富电子芳香化合物与溶于其中的I2发生氧化碘化反应，反应不使用有机溶剂。本碘化反应的转化率和选择性高，主产物为单碘代化合物，碘原子位阻定位效应良好。%A Fe(NO3 ) 3 catalyzed aerobic oxidative iodination of electron-rich arenes was achieved by reaction of the molten arenes with I2 which dissolved in the former,using molecular oxygen as an oxidant with high conversion and selectivity.The main product of the reaction is monoiodoarene with good orientation effects due to the large size of the iodine atom .
