title: 8,9-Didehydrofluoranthenes as building blocks for the synthesis of extended polycyclic aromatic hydrocarbons (PAHs).
abstract: [reaction: see text] The synthesis of phenyl-substituted 8,9-dibromofluoranthene and p-dodecylphenyl-substituted 8,9-fluoranthene anthranilic acid is presented. Their synthetic potential as 8,9-didehydrofluoranthene precursors is demonstrated in combination with a new biscyclopentadienone by the synthesis of novel phenyl-substituted PAHs with up to 14 annulated rings. The crystal structure of 7,16-diphenylfluorantheno[8,9-k]fluoranthene is given.
