title: Synthesis of large polycyclic aromatic hydrocarbons from bis(biaryl)acetylenes: large planar PAHs with low π-sextets.
abstract: A new synthesis of large PAHs with low Clar sextets was developed. This synthesis involves initial bis(biaryl)acetylene 1, which undergoes initial ICl-aromatization and a subsequent Mizoroki-Heck coupling reaction to give dibenzochrysene derivative 3 that can be transformed into planar PAHs 4 using DDQ-oxidation.
