4.Synthesis of 9-Bromo-10-phenylanthracene

A mixture of 9,10-dibromoanthracene, phenylboronic acid and tetrakis(triphenylphosphine) palladium was added to an air-free two-phase mixture of THF and aqueous 2 M K2CO3. The resulting mixture was vigorously stirred under nitrogen atmosphere at 80 ℃ for 8 h. The organic layer was separated and the aqueous phase was extracted with dichloromethane , the combined organic layer was washed with brine and dried over anhydrous MgSO4. The solvent was evaporated under reduced pressure to give an light-yellow solid, which was further purified with column chromatography using petroleum ether/dichloromethane as eluant to afford the target product.
