“…Certain olefin complexes in which the EAN for the metal is being exceeded will readily undergo oxidation 0 or other reactions in which less involvement of electrons (and/or ligand atoms) with the metal are observed. The action of CC14 on cobaltocene (32) and (25) serves to illustrate this principle, (LIII). Some of the reactions of nickelocene also follow this principle, such as (LIV) (37), (LV) (19), and (LVI) (51).…”
