5,6,11,12,17,18-hexadehydro-1,4,7,10,13,16-hexaethynyltribenzo[a,e,i]cyclodod ecene: Synthesis and CpCO-catalyzed cycloisomerization to the first superdelocalized oligophenylenes

The largest subunit of the carbon allotrope 'graphyne', title compound 1, is also a potential precursor to circular [6]phenylene, antikekulene. Single and double CpCo-catalyzed cycloisomerization provided the respective angular [3]- and [5]-phenylenes. Th
