Reaction Steps

Next, 3 g (11 mmol) of cyclopenta[cd]pyrene-3,4-dione and 2.3 g (11 mmol) of 1,3-diphenylacetone were added to 300 mL of an ethanol/toluene (10/1) solution. Under stirring, 52 mL of 6 N aqueous potassium hydroxide was added dropwise thereto. After the completion of the dropwise addition, the mixture was heated to 50° C., stirred for 1 hour, and cooled. The resulting precipitate was filtered, washed with water, ethanol, and isopropyl alcohol, in that order, and dried by heating under reduced pressure to give 2.85 g of 9,11-diphenyl-10H-pentaleno[1,2,3-cd]pyren-10-one as a black solid.
