[10]annulene derivatives are typically non-planar and non-aromatic, with aromatic planar variants suffering from kinetic instability. Now, the synthesis of a planar and aromatic dehydro[10]annulene featuring a fused cyclopropane and an internal alkyne is reported. The resulting hydrocarbon is bench stable and can be stored for extended periods of time.
