The formation of a C[BOND]C bond has been achieved through the cleavage of the sp2 C[BOND]O bond of aryl/alkenyl ethers catalyzed by a nickel complex, and by using Grignard reagents as nucleophiles (see scheme). This method displays a broad substrate scope and leads to good to excellent yields of the aryl–aryl or alkenyl–aryl cross-coupling products.
