Research output: Contribution to journalArticle


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. Their spectroscopic data indicate that they harbor superdelocalization.
