开发了一种制备多相钯催化剂的新方法，称为“聚合物嵌段（PI）法”。该方法操作简单，制备的钯催化剂（PI Pd）对加氢、碳-碳和碳-氧键形成反应具有很高的活性。值得注意的是，PI Pd的活性高于均相Pd催化剂，并且PI Pd通过简单过滤即可回收并重复使用多次而不会损失活性。该催化剂有望取代许多多相钯催化剂，特别是学术界和工业界常用但回收困难的Pd/C。
A new method named “the polymer incarcerated (PI) method” for preparing a heterogeneous palladium catalyst has been developed. The method is operationally simple, and the Pd catalyst prepared (PI Pd) is highly active for hydrogenation, carbon−carbon, and carbon−oxygen bond-forming reactions. Remarkable points are that the activity of PI Pd is higher than that of homogeneous Pd catalysts and that PI Pd is recovered by simple filtration and reused several times without loss of activity. The catalyst is expected to replace many heterogeneous palladium catalysts, especially Pd/C, which is often used in academia and industry, but recovery of which is difficult.
