Versuchsvorschrift

A flask was charged with 9.1 g of fluoranthene-3-boronic acid, 10.5 g of 3-iodobromobenzene, 2.1 g of tetrakis(triphenylphosphine)palladium(0), 186 mL of toluene, and 74 mL of a 2 M sodium carbonate aqueous solution in an argon atmosphere. The mixture was stirred at 100° C. for 8 hours. After cooling the reaction solution to room temperature, the reaction solution was extracted with toluene. After removing the aqueous phase, the organic phase was washed with a saturated sodium chloride solution, and dried over anhydrous sodium sulfate. After filtering the organic phase, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 9.2 g of the target 3-(3-bromophenyl)fluoranthene (yield: 70%).
