Total syntheses and structures of angular [6]- and [7]phenylene: The first helical phenylenes (heliphenes)

Two plus two plus two times two: A double cobalt-catalyzed cycloisomerization was used to convert appropriate hexaynes into hydrocarbons 1 and 2. Their x-ray structures reveal pronounced helical topologies, but their barriers to enantiomerization are low
