The rhodium-catalyzed hydroformylation reaction of methylene- and alkylidenecyclopropanederivatives proceeds under mild conditions to lead to the exclusive formation of linear aldehydes and the stereointegrity of the quaternary carbon center remains unaffected in the process.

An efficient and reusable polystyrene-supported η5-cyclopentadienyl rhodium catalyst is prepared and applied to the synthesis of substituted cyclopentanones either via hydrocarbonylative cyclization starting from 1,4-dienes or from allyl vinyl ethersviatandem Claisen rearrangement and intramolecular hydroacylation of the 4-pentenal intermediates.
