Reaktionsschritte
22.5 g of 9-bromoanthracene, 15.8 g of 2-naphthelene boronic acid and 2.0 g of tetrakis(triphenylphophine)palladium were mixed, followed by argon displacement. After adding 150 ml of toluene and 140 ml of 2M sodiumcarbonate aqueous solution thereto, it was refluxed on heating for 7 hours. After standing to cool, the crystal precipitated was filtrated it was washed by ethanol and toluene. The crystal obtained was recrystallized in toluene, followed by filtering and drying, and then 23.1 g of 9-(naphthalene-2-yl)anthracene was obtained (yield: 87%).
