Recent efforts in our group tostudy the reactivity of complexes of common, abundant arenes and aromaticheterocycles of {TpW(NO)(PMe3)} have led to the synthesis of large classes of functionalized smallmolecules.  We now turn our attention to polyaromatichydrocarbons, which present many sites for potential chemical elaboration.  Procedures to synthesize ?2complexes of naphthalene and anthracene have been developed, with bindingoccurring preferentially at C3 and C4. Investigation into the scope of reactivity of these complexes isunderway.Tandem protonation andnucleophilic addition reactions have generated new 1,2-dihydronaphthalene andanthracene complexes under mild conditions. Nucleophiles successfully added regio- and stereoselectively under theseconditions include pyrrole, indole, and 2,3-dimethylfuran.  Diels-Alder-type cycloadditions proceed withselect dienophiles.  The organictransformations possible with this methodology lead to new types of novelorganic ligands.
