The dimethylsilylcyclopentadienide anion undergoes cleavage of the silicon-cyclopentadienyl bond upon attempted complexation with transition metals.Complexes bearing such ligands can be obtained by metallation of the cyclopentadienyl ligand in tricarbonyl(η⁵-cyclopentadienyl)manganese, ferrocene and ruthenocene, followed by reaction with chlorodimethylsilane.The silicon-hydrogen function can react with carbonyl cobalt or carbonyl(hydrido)tris(triphenylphosphine)iridium, to give heterobimetallic complexes in which cyclopentadienyldimethylsilane acts as an assembling ligand.Similar complexes are obtained starting from tricarbonyl(η⁶-benzene)chromium.
