Participants

Reaction Steps

Under an atmosphere of argon, 9-bromo-10-(3,5-diphenylphenyl)anthracene (3.9 g, 8.0 mmole), 4-(2,2-diphenylvinyl)phenylboric acid (2.7 g, 9.0 mmole, 1.1 eq) and tetrakis(triphenylphosphine)palladium(0) (0.18 g, 0.16 mmole, 2% Pd) were suspended in toluene (30 ml). To the obtained suspension, a 2M aqueous solution of sodium carbonate (2.9 g, 27 mmole, 3 eq/15 ml) was added, and the resultant mixture was refluxed for 10 hours. An organic layer was separated from the reaction mixture, washed with a saturated aqueous solution of sodium chloride (30 ml) and dried with magnesium sulfate. After the solvent was removed by distillation, a brown solid substance was obtained. The obtained solid substance was purified in accordance with the column chromatography (silica gel/hexane+10% dichloromethane, hexane+20% dichloromethane), and a white solid substance (4.3 g, the yield: 81%) was obtained. The result of examination of the obtained product in accordance with 1H-NMR was as follows:
