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 ethers via tandem Claisen rearrangement and intramolecular hydroacylation of the 4-pentenal intermediates.
