実験手順

About 100 grams (0.434 moles) pyrene-1-carboxaldehyde, about 28.7 grams (0.434 moles) malononitrile, about 10.4 milliliters acetic acid, about 3.48 grams ammonium acetate and about 400 milliliters benzene are heated to boiling under reflux conditions for 30 minutes. The entire contents of the flask crystallized, forming a deep orange red product which is soluble in tetrahydrofuran, moderately soluble in ethanol and very soluble in chlorobenzene. This product is recrystallized from a mixture of chlorobenzene and ethanol (30:70). Yield: 104.4 grams m. p 248°-250° C.
