In continuing our efforts to develop economical and ecofriendly synthetic protocols, we present a proline-palladium catalyst supported on magnetic nanoparticles (0.5 mol %) for oxidation by molecular oxygen. The supported Pd catalyst shows high activity in the oxidation of alcohols into the corresponding carbonyl compounds where easy catalyst recovery and excellent recycling efficiency are observed. It is possible to recover and reuse the grafted palladium catalysts at least eight times without significant loss of its catalytic activity.
在持续努力开发经济且环保的合成方法的过程中，我们展示了一种负载于磁性纳米颗粒上的脯氨酸-钯催化剂（0.5 mol%）用于分子氧氧化反应。这种负载型钯催化剂在将醇氧化为相应羰基化合物的反应中表现出高活性，在此过程中可轻松回收催化剂且回收效率极佳。接枝的钯催化剂能够回收并重复使用至少八次，而其催化活性无显著损失。
