    • 3. The vial was heated under selected microwave conditions (∼250 W output) for two times, each for 10 min. After irradiation, the polymer was taken out by filtration, washed successively with degassed water, acetone and ether, and dried in vacuo at 50°C to give the supported ligand 3, which was characterized by IR analysis. The loading value was determined to be 0.314 mmol/g by nitrogen elemental analysis.

    • 2 (5 mg, 0.022 mmol) was added in one portion to the resulted suspension at ambient temperature, and the mixture was stirred at room temperature for an additional 2 h. The polymer was taken out from the mixture by filtration, washed successively with dichloromethane, ethanol and acetone to ensure exclusive removal of the unbound metal. Drying at 50°C in vacuum afforded the supported catalyst 4 as a yellowish solid. The palladium content was determined to be 0.665 wt % by Graphite Furnace Atomic Absorption (GFAA) analysis.
