Imposing Curvature on a Polyarene by Intramolecular Palladium-Catalyzed Arylation Reactions:  A Simple Synthesis of Dibenzo[<i>a</i>,<i>g</i>]corannulene

Palladium catalysis has been found to offer an effective solution-phase alternative to gas-phase flash vacuum pyrolysis as a method for converting the planar ring system of 7,10-di(2-bromophenyl)fluoranthene (<b>4</b>) to that of the C<sub>28</sub>H<sub>14</sub> bowl-shaped fullerene fragment dibenzo[<i>a</i>,<i>g</i>]corannulene (<b>5</b>).
