Katalytische Doppelrolle : Hoch substituierte Cyclohexenone entstehen aus cyclopropylsubstituierten Propargylestern unter Einwirkung von [{Rh(CO) 2 Cl} 2 ]. Der Metallkatalysator vermittelt die 1,3‐Acyloxy‐Verschiebung in den Propargylestern und die anschließende hoch regioselektive [5+1]‐Cycloaddition der resultierenden Allenylcyclopropane in Gegenwart von CO.
