A highly efficient meta-selective C−H arylation of aryl ethers has been realized by a new catalytic system based on palladium/norbornene (Pd/NBE) and an S,O-ligand. The reaction proceeds with a broad range of aryl ethers. For the first time, unsymmetrical meta-diarylation of aryl ethers was accomplished using a novel norbornene. The isolation of palladium intermediates provides insight to the mechanism

Since our initial motivation for this work was the development of rhodium catalysts for the activation of C–C bonds adjacent to ketones, this communication serves to identify other, perhaps less obvious, pathways for the reactions of unsaturatedketone compounds by the action of rhodium catalysts.
