Five kinds of polymer-anchored aminophosphine-rhodium complexes were synthesizedby ionic and covalent bonding methods. These anehored rhodium complexes synthesizedpossess good catalytic activity and aldehyde-formation selectivity in the hydroformylationof diisobutylene. The complexes anchored via covalent bonds on polymers showedexcellent reproducibility on recycling. After reaction, it indicated that the loss of rhodiumof the catalysts was very small as shown by analysis.
