Vorschrift

9-bromo-13,13-dimethyl-6,11-diphenyl-11,13-dihydro-6H-indeno[1,2-b]anthracene-6,11-diol (4.19 g, 0.0075 mol), potassium iodide (12.45 g, 0.075 mol), and sodium hypophosphite (6 g, 0.037 mol) were placed in a flask, and were suspended in acetic acid (200 ml). The reaction mixture was stirred for five hours while heating. After the reaction was terminated, the reaction solution was added to an excess of distilled water. The resultant solid was washed with distilled water, filtered, and purified by column chromatography to give 9-bromo-13,13-dimethyl-6,11-diphenyl-13H-indeno[1,2-b]anthracene (2.9 g, yield=74%).
