Reaction Steps

9.8 grams of the benzo(c) flurenone were dissolved in 200 ml of terahydrofuran and hydrogenated in the presence of 0.5 g of a palladium carbon catalyst containing 10 wt % palladium under atmospheric pressure and room temperature. The resulting product was dried over Na2SO4, the solvent removed and the residue extracted with pentane and filtered over silica gel. Colorless platelettes of 3,4-benzofluorene, also sometimes referred to as benzo(c) fluorene, were recovered.
