[反应：见正文]利用聚合物包埋(PI)法，使用新型磷化聚合物对钯催化剂进行了固定化。这种磷化的PI-Pd催化剂在铃木-宫浦偶联反应中表现出良好的活性，而不需要添加外加的膦配体。在该反应中没有Pd的浸出，催化剂通过简单的过滤得到了定量的回收，并多次重复使用而不会失去活性。
[reaction: see text] Immobilization of a palladium catalyst with use of new phosphinated polymers was carried out utilizing the polymer incarcerated (PI) method. This phosphinated PI Pd catalyst showed excellent activity in Suzuki-Miyaura couplings without addition of external phosphine ligands. No leaching of Pd was observed in this reaction, and the catalyst was recovered quantitatively by simple filtration and reused several times without loss of activity.
