Carbonylative Suzuki–Miyaura Coupling of Arylboronic Acids with Aryl Iodides Catalyzed by the MCM‐41‐Supported Bidentate Phosphane Palladium(II) Complex

The first heterogeneous carbonylative Suzuki–Miyaura cross‐coupling reaction of arylboronic acids with aryl iodides under an atmospheric pressure of carbon monoxide has been achieved in anisole at 80 °C in the presence of a catalytic amount of an MCM‐41‐supported bidentate phosphane palladium(II) complex (MCM‐41‐2P‐PdII), yielding unsymmetrical biaryl ketones in good‐to‐high yields. This polymeric palladium catalyst exhibited higher activity and selectivity than [PdCl2(PPh3)2] and can be reused at least 10 times without any decrease in activity. (© Wiley‐VCH Verlag GmbH & Co.
