Carbonylative Suzuki–Miyaura coupling catalyzed by palladium supported on aminopropyl polymethylsiloxane microspheres under atmospheric pressure of CO

• High catalytic activity of palladium supported on polysiloxane microspheres in Suzuki reaction.
• High catalytic efficiency at low amount of Pd.
• Good selectivity to different substituted benzophenones at low CO pressure.

Carbonylative Suzuki–Miyaura cross-coupling reactions of various aryl iodides with phenylboronic acids were catalyzed by palladium supported on amino-modified silica microspheres. Reactions performed with a very low concentration of Pd, under the atmospheric pressure of CO, led to high/moderate yields of multiple benzophenones.
