RHODIUM CATALYZED CARBONYLATION REACTIONS OF CYCLOPROPANES

Article abstract of DOI:10.1246/cl.1980.753

Cyclopropane was carbonylated by 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.
