Reaction Conditions

Reaction Steps

25.4 g (100 mmol) of 9-bromoanthracene, 12.8 g (105 mmol) of phenylboronic acid, 0.233 g (1.00 mmol) of palladium(II) acetate, and 0.913 g (3.00 mmol) of tri(ortho-tolyl)phosphine were put into a 500 mL three-neck flask, and nitrogen substitution in the flask was carried out. Then, 100 mL of ethylene glycol dimethyl ether (abbreviation: DME) and 75 ml (150 mmol) of a potassium carbonate aqueous solution (2.0 mol/L) were added to this mixture. This solution was refluxed under a nitrogen gas stream at 90° C. for 6 hours. After completion of a reaction, a precipitate in the reaction mixture was collected by suction filtration. When an obtained solid was recrystallized with a mixed solvent of chloroform and hexane, 20.8 g of a white, powdery solid of 9-phenylanthracene, which was a target matter, was obtained with the yield of 82%.
