3-(4H-Cyclopentaphenanthrylidene)-1,5-bis-(trimethylsilyl)-1,4-pentadiyne (3) was synthesized and converted by hydropyrolysis into corannulene (1) besides others in reasonable yields.It represents a new route of the simplest bowl-shaped polycyclic aromatic hydrocarbon starting from an easily accessible precursor.
