The first heterogeneous carbonylative Stillecouplingreaction of organostannanes with aryl iodides under an atmospheric pressure of carbon monoxide has been achieved in DMF at 80 °C in the presence of a catalytic amount of an MCM-41-supported bidentate phosphine palladium(0) complex [MCM-41-2P-Pd(0)], yielding a variety of unsymmetrical ketones in good to high yields. This polymeric palladium catalyst
