实验步骤: Under an atmosphere of argon, 9-bromo-10-(4-(2-phenylvinyl)-phenyl)anthracene (3.1 g, 7.1 mmole), 4-(2,2-diphenylvinyl)phenylboronic acid (2.4 g, 8.0 mmole, 1.1 eq) and tetrakis(triphenylphosphine)-palladium(0) (0.16 g, 0.14 mmole, 2% Pd) were suspended into toluene (25 ml). To the obtained suspension, a 2 M aqueous solution of sodium carbonate (2.5 g, 24 mmole, 3 eq/12 ml) was added and the resultant mixture was heated under refluxing for 10 hours. The reaction mixture was filtered and washed with water and methanol and a yellow solid was obtained. The obtained solid was suspended in boiling toluene (50 ml), cooled while being left standing, filtered and washed with toluene and a light yellow solid (3.8 g, 88%) was obtained. under refluxing for 10 hours The reaction mixture was filtered washed with water and methanol a yellow solid was obtained cooled while being left standing filtered washed with toluene

实验步骤: Under an atmosphere of argon, 9-bromo-10-(4-bromophenyl)-anthracene (3.0 g, 7.3 mmole), 4-(2,2-diphenylvinyl)phenylboronic acid (6.6 g, 22 mmole, 3 eq) and tetrakis(triphenylphosphine)palladium(0) (0.34 g, 0.29 mmole, 2% Pd) were suspended into toluene (60 ml). To the obtained suspension, a 2 M aqueous solution of sodium carbonate (7.0 g, 66 mmole, 3 eq/35 ml) was added and the resultant mixture was heated under refluxing for 10 hours. The reaction mixture was filtered and washed with toluene, water and methanol and a gray solid (1.4 g, the first crop, 25%) was obtained. From the filtrate, the organic layer was separated, washed with a saturated aqueous solution of sodium chloride and dried with magnesium sulfate. The solvent was removed by distillation and a deep brown oil was obtained. When the obtained oil was dissolved in dichloromethane, crystals were formed soon. The formed crystals were separated by filtration and washed with a mixed solvent composed of hexane and dichloromethane and a white solid (3.3 g, the second crop, 59%) was obtained. The obtained crude crystals (3.5 g) were suspended in boiling toluene (40 ml), cooled while being left standing, filtered and washed with toluene and a light yellow solid (2.4 g) was obtained. under refluxing for 10 hours The reaction mixture was filtered washed with toluene, water and methanol a gray solid (1.4 g, the first crop, 25%) was obtained From the filtrate, the organic layer was separated washed with a saturated aqueous solution of sodium chloride dried with magnesium sulfate The solvent was removed by distillation a deep brown oil was obtained crystals were formed soon The formed crystals were separated by filtration washed with a mixed solvent a white solid (3.3 g, the second crop, 59%) was obtained The obtained crude crystals (3.5 g) cooled while being left standing filtered washed with toluene
