The general procedure for the synthesis of 1,1,4,4,7,7,10,10-octamethyl-2,3,4,7,8,9,10,12-octahydro-1H-dibenzo[b,H]fluorene from fluorene and 2,5-dichloro-2,5-dimethylhexane was carried out as follows: a 1 L round bottom flask was charged with fluorene (18 g, 0.108 mol) and 2,5-dichloro-2,5-dimethylhexane ( 2.0 eq, 40 g), followed by the addition of 300 ml of nitromethane as solvent and initiation of stirring. Aluminum trichloride (1.33 eq., 19.2 g) was slowly added to the reaction mixture at room temperature. After the reaction was stirred continuously for 20 h at room temperature, 350 ml of cold water was added slowly and dropwise to the reaction solution and formation of purple precipitate was observed. The precipitate was collected by filtration and the resulting solid was dissolved in 250 ml of boiling ethanol to remove impurities, filtered and cooled. This purification process was repeated using 150 ml of hexane as solvent. Finally, the white solid was dried under vacuum to give 36.7 g of product in 87% yield. | [References]
