The iodination of chlorinated aromatic compounds using Ag2SO4/I2, AgSbF6/I2, AgBF4/I2, and AgPF6/I2 offers access to iodoarenes that are valuable intermediates in organic synthesis. Specifically, iodination of phenols, anisoles, and anilines with a 3,5-dichloro substitution pattern preferentially yielded the ortho, para, and para iodinated product, respectively. In the case of chlorobenzene and 3-chlorotoluene
使用 Ag 2 SO 4 /I 2、AgSbF 6 /I 2、AgBF 4 /I 2和 AgPF 6 /I 2对氯化芳族化合物进行碘化可提供有机合成中有价值的中间体碘芳烃。具体而言,苯酚、苯甲醚和苯胺以 3,5-二氯取代模式碘化分别优先产生邻位、对位和对位碘化产物。在氯苯和3-氯甲苯的情况下,AgSbF 6 /I 2、AgBF 4 /I 2和AgPF 6 /I 2,但不是Ag 2 SO 4 /I 2,选择性地将碘引入氯取代基的对位。
