We report herein a cerium photocatalyzed aryl migration from an aryl ether to a carboxylic acid group through radical-Smiles rearrangement. This operationally simple protocol utilizes inexpensive CeCl3 as a photocatalyst and converted a variety of 2-aryloxybenzoic acids into aryl-2-hydroxybenzoates in good yields.
我们在此报道了
铈光催化芳基通过自由基-Smiles重排从芳基醚迁移到
羧酸基团。这种操作简单的方案利用廉价的CeCl 3作为光催化剂,并将各种2-芳氧基
苯甲酸转化为芳基-
2-羟基苯甲酸酯,收率良好。
