Zusammenfassung:A process is provided for preparing tricyclopentadienyl cerium as well as the mono and dicyclopentadienyl cerium intermediates which comprises reacting an alkali metal cyclopentadienide with ceric ammonium nitrate, in solution in an inert organic solvent in a manner to obtain either tricyclopentadienyl cerium or to form in sequence, and stepwise, monocyclopentadienyl cerium dinitrate, dicyclopentadienyl cerium mononitrate, and tricyclopentadienyl cerium, depending upon the order of addition of the reactants.
