Vorschrift

Under an argon atmosphere, 29.0 g of phenylboronic acid, 25.7 g of 2,6-dibromoanthracene, 4.62 g of tetrakis(triphenyl phosphine) palladium (0), 800 mL of toluene, and 400 mL of a 2-M aqueous solution of sodium carbonate were loaded, and then the mixture was stirred for 8 hours under reflux. After the mixture had been cooled to room temperature, the precipitated crystal was taken by filtration. The resultant solid was repeatedly recrystallized with toluene and hexane and washed. Thus, 25.0 g of 2-phenylanthracene were obtained (in 75% yield).
