Vorschrift

9-bromo-13,13-dimethyl-6,11-di(naphthalen-2-yl)-11,13-dihydro-6H-indeno[1,2-b]anthracene-6,11-diol (11.87 g, 0.018 mol), Potassium iodide (29.88 g, 0.18 mol), and Sodium hypophosphite (35.63 g, 0.297 mol) were placed in a flask, and were suspended in acetic acid (300 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, filtered and purified by column chromatography to give 9-bromo-13,13-dimethyl-6,11-di(naphthalen-2-yl)-13H-indeno[1,2-b]anthracene (8 g, yield=71%).
