Soluble' star shape polymers containing pyridine ligand at the chain ends, prepared by adopting sequential living ring-opening metathesis polymerizations of norbornene and cross-linking reagent using Mo-alkylidene catalyst via' core-first' approach, have been employed as ligands for Ru catalyzed chemoselective hydrogen transfer reductions of various ketones. The catalyst can be recovered quantitatively, and reused without decreasing in the activity and the selectivity.

以降冰片烯为原料，以mo -烷基烯为催化剂，采用“核优先”方法，采用序贯开活环复分解聚合和交联试剂制备了链端含吡啶配体的可溶性“星形”聚合物，并将其作为配体用于钌催化多种酮类的化学选择性氢转移还原。该催化剂可以定量回收，并且在不降低活性和选择性的情况下重复使用。
