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.
