The C−Holefination of substituted anisole derivatives as limiting reagents has been realized by a Pd/S, O-ligand catalyst providing the olefinated products in good yields and site selectivities. The reaction proceeds under mild conditions with a broad range of substituted aryl ethers bearing both electron-donating and electron-withdrawing substituents.
