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 then cooled to room temperature and poured into ice water (800 mL). Thereafter, the precipitate was filtered and washed with water and ethanol. The precipitate was then re-crystallized from toluene (620 mL) to give 14.49 g of pale yellow flake-like crystals of 2,6-dibromoanthracene (Compound 24).
