The experiments reveal that anchoring rhodium(I) macromolecules containing pendant pyridine groups exhibit remarkably different carbonylation catalytic behaviours, depending on the quaternary degree of polymer ligands. The catalysts with the quaternized ligands are more active than that with the non‐quaternized ligands, but the best of the lots isn't the highestly quaternized. A new structural type of the compounds called the polydentate hetero‐bound rhodium(I) ion complexes is recognized to be responsible for higher carbonylation reactivities.
