Several new bridged trinuclear complexes of the general formula RSi<η⁵-C5H4M(CO)_nR¹>3, have been prepared in good yield from the reaction of the lithiated compounds (η⁵-C5H4Li)M(CO)_nR¹ (M = Mn, W, Fe; R¹ = Me, Et, and benzyl) with various alkyl trichlorosilanes.The crystal and molecular structure of MeSi<η⁵-C5H4Fe(CO)2C2H5>3 is presented.In addition, some limitations of the direct cyclopentadienyl ring metalation are discussed.
