실험 절차

Subsequently, a mixture of 2,6-dibromoanthraquinone (22.41 g, 61.23 mmol), acetic acid (250 mL), 56-58% hydriodic acid (100 mL), and 50% hypophosphorous acid (55 mL) was refluxed for 5 days. The mixture was cooled to RT and poured into ice water (800 mL). The resulting precipitate was filtered, washed with water and ethanol, and recrystallized from toluene (620 mL) to give 2,6-dibromoanthracene: 14.49 g pale yellow flake-like crystals.
