Direct dehydrogenative coupling between the linear ter- and quaternaphthalenes and substituted benzenes was achieved under the Kita conditions using the hypervalent PIFA/BF3 reagent. Products resulting from either the double arylation of the naphthalenic substrate or the formal dimerizative arylation have been prepared. For example, in the latter mode, ternaphthalene was converted into a series of linear octiarenes (counting the capping Ar). The process represents an alternative to the cross-coupling methodologies employed in related syntheses and proceeds via a selective functionalization of six relatively inert aromatic CH bonds.
