文摘

Insertion of benzophenone into the Y−Cp (Cp = C₅H₅) bond and two new reactivity patterns of the Cp-substituted alkoxide complexes have been established, by which an efficient and convenient method for conversion of the unsubstituted cyclopentadienyl group to the single-carbon-bridged ansa-cyclopentadienyl/alkoxyl ligand by using a simple ketone as the functionalizing reagent is developed. All products including the four-center interaction precursor of the insertion have been characterized by X-ray structural analyses.
