Cerium photocatalyzed radical smiles rearrangement of 2-aryloxybenzoic acids

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 CeCl(3) as a photocatalyst and converted a variety of 2-aryloxybenzoic acids into aryl-2-hydroxybenzoate...

Sumario: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 CeCl(3) as a photocatalyst and converted a variety of 2-aryloxybenzoic acids into aryl-2-hydroxybenzoates in good yields.
