diacetylethylene to give substituted bicyclooctadienes as Diels–Alder adducts. Treatment of these with phosphorus pentasulfide gives derivatives of benzenonaphtho[c]thiophenes, which are thiophene analogues of triptycene. Reaction of the anthracenes with dibenzoylacetylene gave substituted bicyclooctatrienes, which on treatment with phosphorus pentasulfide gave inseparable mixtures of the benzenonaphtho[c]thiophenes
