Cyclopropane was carbonylated by [Rh(CO)2Cl]2 under carbon monoxide pressure to give cyclobutanone, dipropyl ketone, propyl isopropyl ketone, and 2- or 3-methylcyclohexanone. Some other cyclopropane derivatives were also examined. Norcarane gave a small amount of bicyclo[4.2.0]octa-7-one, though phenylcyclopropane did not give any carbonylation products. The formation of polyketone was efficient in the case of methylenecyclopropane.
