Cycloheptale[ ef ]heptalene (pleiaheptalene) is the first peri‐annelated [4n]‐π‐electron system without aromatic partial structure . One of its derivatives that has now been synthesized is the compound 1 , RMe, which has exclusively the given double bond distribution. In solution an equilibrium is established with a π‐bond isomer.
