title: Kinetic control in the palladium-catalyzed synthesis of C(2)-symmetric hexabenzotriphenylene. A conformational study
abstract: The hitherto unisolated, thermodynamically unstable C(2)-symmetric conformer of hexabenzotriphenylene (1) has been efficiently synthesized by palladium-catalyzed cyclotrimerization of 9, 10-didehydrophenanthrene (4). The barriers to conformational interconversion of 1 are examined experimentally and by computational studies.
