Vorschrift

9-Bromoanthracene (2.57 g, 10.00 mmol), 2-naphthyl boric acid (1.80 g, 12.65 mmol) and sodium carbonate (2.34 g, 22.1 mmol) were suspended in a mixture of toluene (20 mL), ethanol (3 mL) and water (10 mL). To the suspension, was added tetrakis(triphenylphosphine)palladium (0.25 g, 0.22 mmol). The mixture was stirred under reflux for about 24 hours, and then the refluxed mixture was cooled to room temperature. The organic layer was separated and washed with water, and the aqueous layer was extracted by chloroform. The organic extract was dried over magnesium sulfate, and concentrated in vacuo to prepare a 9-(2-naphthyl)anthracene compound C-1 (2.55 g, yield 84).
