Versuchsvorschrift

Under the atmosphere of argon, 2.7 g of fluoranthene-3-boronic acid, 2.0 g of 6-bromo-2-naphthol, 0.31 g of tetrakis(triphenylphosphine)palladium (0), 27 mL of 1,2-dimethoxyethane and 13.5 mL of an aqueous 2M sodium carbonate solution were placed in a flask, and the resulting mixture was stirred under reflux while heating for 4 hours. After cooling to room temperature, 2M hydrochloric acid was added to the reaction solution to allow it to be acidic, and the reaction solution was extracted with dichloromethane. An aqueous phase was removed and an organic phase was washed with saturated saline, and dried with anhydrous sodium sulfate. After filtration, the solvent was distilled off under reduced pressure, residues were dispersed and washed with dichloromethane, whereby 2.75 g (yield 89%) of 6-(fluoranthen-3-yl)-2-naphthol as an intended product was obtained.
