    • 2 (0.5 equiv, 60 mg) was dissolved in DMSO (10 mL) by using sonicator and then added into the dispersion of PS-PEG-NHC resin. The resulting dispersion was stirred for 3 h at 50 °C. After the temperature was increased to 100 °C, the resin mixture was stirred for further 30 min. The PS-PEG-NHC-Pd was washed with DMSO (20 mL × 3), DMF (20 mL × 3), THF (20 mL × 3), distilled water (20 mL × 5), 1 N-HCl / THF (20 mL × 5), methanol (20 mL × 5) and dried under reduced pressure.

    • 3 (820 mg, 2.5 mmol) in distilled water (4 mL), and then aryl halide (0.5 mmol) was added to the mixture. The resulting dispersion was stirred for 12 h at 50 °C. The catalyst was filtered and washed with distilled water and diethyl ether. The product was extracted with diethyl ether and purified by column chromatography. The yield was calculated from the mass value of the product after isolation with column chromatography.
