Abstract
The first heterogeneous carbonylative cross-coupling reaction of aryl halides with sodium tetraphenylborate under an atmospheric pressure of carbon monoxide was achieved in DMF at 80 °C or 130 °C in the presence of a catalytic amount of MCM-41-supported bidentate phosphine palladium(II) complex [MCM-41-2P-Pd(II)] to yield unsymmetrical biaryl ketones in good to high yields. This polymeric palladium catalyst can be reused many times without any decrease in activity.
