A convenient and simple method for copper-catalyzed synthesis of 2-(arylthio)phenols through C–H functionalization of arylthiols and aryl iodides was developed under ligand-free conditions without nitrogen protection. In addition, arylthioquinone derivatives were very easily prepared for one more step of oxidation with moderate to good yields. This provide an alternative and efficient way to 2-(arylthio)phenols
在没有氮保护的无配体条件下,开发了一种方便,简单的铜催化芳基硫醇和芳基碘化物通过CH官能化合成2-(芳硫基)酚的方法。另外,非常容易地制备芳基硫醌衍生物以进行另一步氧化,产率中等至良好。这提供了一种平稳有效的2-(芳硫基)苯酚和芳硫基苯醌衍生物的替代方法,而无需使用配体和氮保护剂或昂贵的芳基硼酸。
