高分子配位体具有稳定化或保持配位不饱和的活性中心的潜在能力。Grubbs等将二茂钛二氯化物固定在聚苯乙烯骨架上,获得活性较相应的均相催化剂高六、七倍的高分子氢化催化剂。其后,研究工作大多是沿着将结构和组成确定的可溶性金属络合物通过不同途径联接在高分子骨架上进行的。根据江英彦等以及我们自己的有关高活 Macromolecular ligands have the potential to stabilize or maintain an active center that is coordinately unsaturated. Grubbs et al. Immobilized titanocene dichloride on a polystyrene skeleton to obtain a polymer hydrogenation catalyst having six or seven times higher activity than the corresponding homogeneous catalyst. Since then, much of the work has been done by linking soluble metal complexes of defined structure and composition through different routes to the polymer backbone. According to Jiang Ying-yan, etc. and our own about high living
