Synthesis of new halogenated pentiptycene building blocks.
The synthesis of central-ring halogenated pentiptycene phenols 12-14 and dihalogenated pentiptycenes 15-17 is reported. Their utilities as building blocks for preparing new pentiptycene-derived pi-conjugated systems through the Sonogashira, Heck, and Suzuki reactions are also demonstrated.
