Abstract: Synthesis of molecules combining both fullerene and metallocene moieties separated by some spacer is discussed in connection with the possible intramolecular charge transfer. Two new kinds of spacers, =CH-CO- and -Pd-P-, have been introduced by using the corresponding reactions. Reaction of diazoacetyl ferrocene and cymantrene with C₆₀ has been studied in detail and products characterized. 1,1'-Bis (diazoacetyl) ferrocene gave with C₆₀ 1:1 adduct to which the ansa-structure has been assigned on the basis of ¹H and ¹³C NMR spectra. Palladium-h²-C₆₀ complex with a bidentate ferrocenyl diphosphine as a ligand has been also prepared.
