title: Large phenyl-substituted acenes by cycloaddition reactions of the 2,6-naphthodiyne synthon.
abstract: Phenyl-substituted tetra-, penta-, hexa- and octacenes were easily obtained starting from a readily available naphthalene-based bisaryne precursor. This approach to large acenes involves a sequence of two Diels-Alder cycloadditions with dienones followed by two CO extrusion reactions.
