In a 1000 ml three-necked flask that had been deaerated and filled with nitrogen, 4.4 g (8.1 mmol) of 3,7-bis(5-methoxybiphenyl-2-yl)dibenzo[b,d]thiophene was dissolved in anhydrous dichloromethane (400 ml), 13.2 g (81 mmol) iron(III)chloride was then added, and the mixture was stirred one hour. Methanol 200 ml were added to the mixture and the organic layer was separated and the solvent removed in vacuum. The residue was purified by column chromatography on silica(hexane-dichloromethane) afforded a white solid (4.1 g, 7.5 mmol, 93%).
