摘要： Polymer bound multidentate complexes are prepared by reacting pendant benzyl chloride and benzyl iodide groups on a variety of polymer supports, including crosslinked polystyrene, with 3,3'-iminodiproprionitrile and reducing the nitrile groups by treatment with, for example, a boron hydride-tetrahydrofuran complex to form the amine. The amine is a precursor for other ligand systems; for example, the primary amine groups formed condense with an aldehyde or ketone to yield five coordinate Schiff base ligands. The polydentate amine ligand systems are useful for synthesis of chelating agents for sequestering metal ions from solution for purification or concentration purposes. Metal complexes of these ligands with manganese, iron, cobalt, nickel, copper, and zinc can be prepared which are useful as heterogeneous oxidation catalysts.
