The Pd(II) complexes strongly chelated by two β-iminoenolate ligands were easily synthesized in only two steps, and purified based on their sublimable and highly stable property. The Pd(II) complexes anchored on a silica surface showed good catalytic activity in Suzuki-Miyaura reactions (up to 99% yield with 0.05 mol% catalyst). They tolerated a wide range of temperature (rt∼110 °C) and various solvents, and could be reused multiple times after simple recovering process.

可升华的双（β-亚氨基甲酸）钯（II）配合物及其在铃木-宫浦反应中的催化剂应用

被两个β-亚氨基烯酸酯配体强烈螯合的Pd（II）络合物仅需两步即可轻松合成，并基于其可升华和高度稳定的特性进行纯化。锚固在二氧化硅表面的Pd（II）配合物在Suzuki-Miyaura反应中显示出良好的催化活性（使用0.05 mol％的催化剂，收率可达99％）。它们耐受温度范围广（rt〜110°C）和各种溶剂，并且经过简单的回收过程即可重复使用多次。
