A family likeness : The seven‐sided homologue of kekulene, septulene (see structure), has been synthesized in seven steps by ring‐closing metathesis. Its properties (spectroscopic and structural) are strikingly similar to those of kekulene despite its sevenfold symmetry and resulting non‐alternant structure. The chair‐type conformation in the crystal arises from packing forces. Septulene is probably a free pseudorotor in the gas phase.
