Reaction of η5-C5H5Fe(CO)2SiMe3 with either n-BuLi or lithium diisopropylamide (LDA) results in a migration of the trimethylsilyl group from iron to the complexed Cp ligand. The resulting η5-C5H4SiMe3Fe(CO)2 anion is readily alkylated to give σ-bonded derivatives. The unique reactivity of the trimethylsilyl systems is underscored by comparison with the behavior of η5-C5H5Fe(CO)2Me under identical conditions
