| Outline of Final Research Achievements |
Reactions for synthesis of crowded conjugated molecules as polycyclic aromatic hydrocarbon (PAH) precursors were investigated. Rhodium-catalyzed annulation of diynes and 2 equivalents of biphenylboronic acids through C-H cleavage was optimized to afford 1,4-bis(10-arylphenanthrene-9-yl)benzenes. Oxidative cyclization of the obtained compounds gave non-planar PAHs with green fluorescence.
Moreover, ruthenium-catalyzed annulation of 1-naphthylsilanes and alkynes through C-H cleavage, was developed to prepare silaphenalenes which are kinds of silicon-containing PAHs.
