Vorschrift

An amount of 15.14 g (58.9 mmol) of 9-bromoanthracene, 7.2 g (59 mmol) of phenylboronic acid, and 1 g of tetrakis triphenylphosphine palladium as catalysis were dissolved in a mixed solvent of 100 ml of toluene and 25 ml of ethanol. Then, 50 ml of 2M sodium carbonate solution was added to the mixed solvent and allowed to react at 90° C. for 12 hours. After the reaction was completed, the organic layer was separated and purified by column chromatography to obtain 13.65 g (53.7 mmol) of 9-phenylanthracene. The yield was 91.2%.
