The total syntheses of furan and thiophene PAH's related to acephenanthrylene are reported. Cyclobutanones which were obtained by [2 + 2] addition of ketenes with 2,3‐dihydrofuran or 2,3‐dihydrothiophene regioselectively could be converted into angular PAH skeleton molecules by rearrangements with polyphosphoric acid. 2,3‐Dichloro‐5,6‐dicyanobenzoquinone was applied for aromatization to achieve the formation of PAH's.
