    • Transition metal containing composition for use as a bleach catalyst comprising at least one transition metal ion coordinated with at least one chelating ligand to form a complex capable of binding O.sub.2 H.sup.-. The ligand(s) should have at least two strong donor functional groups capable of coordinating with a single one of the transition metal ions in the complexes to form a six-member or larger ring. The complexes are capable of coordinating peroxide groups while the ligand functions to substantially prevent precipitation of hydroxides of the transition metal ions in aqueous alkaline solutions of the transition metal containing composition. A detergent-bleach composition comprising an effective amount of a peroxide bleaching agent and an effective amount of the bleach catalyst described above, and a bleaching agent composition comprising a peroxide compound present in an amount effective to impart a bleaching action and a catalyst present in an effective amount to promote the bleaching action of the peroxide compound comprising the transition metal composition described above are also disclosed, as well as a catalyst present in an effective amount to promote the bleaching action of peroxide compounds in a detergent-bleach composition comprising the transition metal composition described above.

    • 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.
    • 通过使各种聚合物载体(包括交联聚苯乙烯)与3,3'-亚氨基二丙腈反应,将苄基氯和苄基碘基团反应,通过用例如硼氢化物 - 四氢呋喃处理来还原腈基来制备聚合物结合的多齿络合物 复合以形成胺。 胺是其他配体体系的前体; 例如,伯胺基团与醛或酮缩合以产生五配位席夫碱配体。 多齿胺配体体系可用于合成螯合剂,用于从溶液中螯合金属离子用于纯化或浓缩。 可以制备这些配体与锰,铁,钴,镍,铜和锌的金属络合物,其可用作非均相氧化催化剂。
