Palladium-catalyzed cycloaddition reactions of 1,8-diethynylnaphthalene derivatives with o-diiodoarenes take place to generate the corresponding benzo[k]fluoranthene-based linear acenes in moderate to good yields. In addition, 1-ethynyl-8-iodo-naphthalenes undergo palladium-catalyzed cyclodimerizations to produce zethrenes. Finally, in the presence of a catalytic system comprised of [NiBrdppe)/Zn], 1-ethynyl-8-iodonaphthalenes reacts with nitriles and 2-butyne to form the respective pyrroloarenes and pyrene.
