to an increase in catalytic activity and a decrease in regioselectivity toward the linear aldehyde product. Xanthene-based ligands 1a−1c yielded highly active and regioselective hydroformylationcatalysts; ligands containing p-tolyl ether and ferrocene backbones 2a−2c and 3a−3c provided less active and less regioselective catalysts. Catalysts containing benzene-derived ligands 4a and 4b showed a remarkable
