A polystyrene resin supported palladium N-heterocyclic carbene (PS-Pd-NHC) complex was found to promote the carbonylative Suzuki-Miyaura cross-coupling reaction. Thus, the carbonylative Suzuki-Miyaura coupling of iodobenzene 2a with phenylboronic acid 3a was carried out in the presence of PS-Pd-NHC 1 under carbon monoxide atmosphere to give 94% yield of benzophenone (4a).
