Zethrenes were synthesized by Pd-catalyzed cyclodimerization of 1-ethynyl-8-iodonaphthalenes. The structure of these cycloadducts was confirmed by X-ray crystal analysis. The bond lengths and bond alternation in the crystal structures reveal that the central two six-membered rings of the title compounds lack aromaticity.
