A general and simple route to the synthesis of the triptycene derivatives 5,12-dihydro-5,12[1′,2′]-benzenonaphthacene (1), 5,14-dihydro-5,14[1′,2′]-benzenopentacene (2) and 5,16-dihydro-5,16[1′,2′]-benzenohexacene (3) is described. It involves the cycloaddition of appropriate quinone to anthracene and subsequent treatment of the resulting adduct with lithium aluminium hydride, followed by p- toluenesulfonyl chloride in pyridine.
