Metal‐Catalyzed Dealkoxylative C_arylC Cross‐Coupling—Replacement of Aromatic Methoxy Groups of Aryl Ethers by Employing a Functionalized Nucleophile

Abstract

The direct replacement of aromatic methoxy groups with activated carbon nucleophiles would give rise to novel synthetic pathways for targeted and diversity-oriented syntheses. We demonstrate here that this transformation can be achieved in a one-step reaction involving a bifunctional organolithium nucleophile in combination with a CAr OMe bond-cleaving nickel catalyst. The resulting products are stable, α-CH active, and suitable for various further modifications.
