reversible or nearly so for compounds where L is a cyclic diolefine (I–III) or a cyclobutadiene (VI) and for the methylated complexesCo(C5Me5)(C5Me5R) (R = Me, Ph) (VII) and irreversible for CoCp(C5H5Ph) (IV) and the complexes V where L is a divinylborane.

phenyl-cyclopentadienecyclopentadienylcobalt is very easily obtained when a cobalticinium cation reacts with methyl- or phenyl-lithium. Triphenylmethyl tetrafluoroborate abstracts the endo-hydrogen atom from these two complexes, and this enabled us to prepare the corresponding mono-substituted cobalticinium salts.
