Cp*Ru+ pi-complexes of 1,2-dihalo- and 1,2,4,5- tetrahaloaromatics are readily prepared by reaction of the arenes with Cp*Ru(CH3CN)(3)(+)OTf(-). The pi-complexes undergo nucleophilic substitutions with 1 or 2 equiv of 1,2-disubstituted aromatic nucleophiles, leading to symmetrically and unsymmetrically substituted organometallic heterocycles.
