摘要：

A reaction between cyclopentadienylsodium and ethyl benzoate in refluxing THF produces (benzoylcyclopentadienyl)sodium (4) in 70-80% 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, [Rh(CO)2Cl]2 or FeCl2 lead to the respective eta5-benzoylcyclopentadienyl derivatives of these metals, and demonstrate the utility of 3 in organometallic syntheses. Reactions of several of these organometallic ketones with cymantrenyllithium [(eta5-C5H4Li)Mn(CO)3] provide a useful new route to bimetallic compounds.
