Synthesis of polymer-supported palladacycle catalyst

v-di(p-acctato)-bis 3-(diphcnylphosphino)-4-styryl]dipalladiuin(II) (93 mg, 0.1 mmol) was added to a test tube and flushed with nitrogen. A mixture of styrene (62 mg, 0.6 mmol) and benzene (2 mL) was injected into the test tube. Then, a mixture of AIBN (azobisisobutyronitrile) (18 mg, 0.01 mmol) and benzene (1 mL) was injected into the stirring test tube. The reaction mixture was then heated at 70 °C for 40 hours. 

The mixture was concentrated to dryness. The dry solid was repeatedly washed by the solvent (THF/hexane =1 15). The isolated polymer was 0.11 g (66% yield).

7 SYNTHESIS OF 1 - [4-(2-PHEN YLETHYNYL)PHEN YL] ETHAN -1-ONE VIA SONOGASHIRA REACTION BY THE USE OF POLYMER-SUPPORTED PALLADACYCLE CATALYST 

Polystyrene-supported palladacycle catalyst (30 mg, 2 pmol Pd), l-(4-bromo-phenyl)ethan-l-one (0.20 g, 1 mmol), phenylacetylene (0.16 g, 1.5 mmol), and triethylamine (3 mL) were sequentially added into a 15 mL septum-sealed test tube under nitrogen atmosphere. The mixture was then heated at 90 °C for 72 hours.
