The first non‐benzenoid, linearly annelated, tetracyclic system with [4n + 2]‐perimeter and [4n]‐partial structures was obtained by dimerization of the allene derivative 1 via [6 + 2]‐cycloaddition. Subsequent 8π‐electrocyclization yielded a tetraquinane, which could be dehydrogenated to the title compound 2 .
