| Outline of Final Research Achievements |
Azulenes, which show unique photophysical and redox properties derived from their unusual dipolar and π-electron polarizations, are promising components for the construction of advanced functional materials. In this study, we found the efficient dehydrogenative functionalization method of C-H bonds of azulenes with the production of hydrogen as the sole byproduct. The reaction occurred with excellent chemo- and regioselectivities to provide azulene derivatives functionalized at 2-position even without any directing groups. Effective conjugation through the 2-position of the azulene ring was demonstrated by the unique stimuli-responsiveness against acid-base reaction.
