Ferrocylidene ketones (1) and biferrocylidene ketones (2) were prepared by condensation of formyl ferrocene with ketones. Biferrocene (5-10) derivatives were obtained by treatment of lithioferrocene with phthalic anhydride, methyl benzoate and/or phenyl iodide respectively. The PMR and IR of these compounds are described.
