The dilithiation of [Co(η4-C4Me4)(η5-C5H5)] to give [Co(η4-C4Me3CH2Li)(η5-C5H4Li)]·PMDETA and the subsequent synthesis and characterization of the CH2-SiR2-bridged [2]cobaltoarenophanes is reported. This is the first development in the chemistry of neutral 18-electron metalloarenophanes featuring a group 9 transition metal.
