A series of cyclopalladated anils of benzoylferrocene with the general formula (Ar = a variety of substituted phenyls and β = naphtyl) were synthesized by transmetallation reaction of the corresponding cyclomercurated derivatives with lithium tetrachloropalladate or by direct cyclopalladation reaction of the corresponding ferrocenylketimines <(η⁵-C5H5)Fe(η⁵-C5H4CPh=NAr)>, followed by the treatment of the resulting products with triphenylphosphine.The composition and the structure of the metallocycles were characterized by elemental analysis, IR, 1H NMR and two-dimensional NOESY spectra.Some spectral features of these complexes were also discussed.Keywords: Palladium; Iron; Mercury; Cyclopalladation; Transmetallation; Ferrocene
