Article abstract of DOI:10.1016/0022-328X(93)80132-U

A reaction between cyclopentadienylsodium and ethyl benzoate in refluxing THF produces (benzoylcyclopentadienyl)sodium (4) in 70-80percent yield.Subsequent treatment of 4 in ethanol solution with thallium ethoxide affords (benzoylcyclopentadienyl)thallium (3) in nearly quantitative yield.Reactions of 3 with Mn(CO)5Br, Re(CO)5Br, 2 or FeCl2 lead to the respective η⁵-benzoylcyclopentadienyl derivatives of these metals, and demonstrate the utility of 3 in organometallic syntheses.Reactions of several of these organometallic ketones with cymantrenyllithium<(η⁵-C5H4Li)Mn(CO)3> provide a useful new route to bimetallic compounds.
