title: A new strategy for ring modification of metallocenes: carbodiimide Insertion into the eta(5)-Y-C5H5 bond and subsequent isomerization.
abstract: Unusual insertion of carbodiimide into the Y-Cp (Cp = C(5)H(5)) bond and isomerization of the resulting cyclopentadienyl (Cp)-substituted amidinate complex to the amidino-substituted Cp complex have been established, representing an efficient and simple method for ring modification of sensitive metallocenes. All products, including the rare four-center interaction precursor of the insertion, have been characterized by X-ray structural analyses.
