Preparation of a Cobalt Analogue of Verdoheme by Coupled Oxidation of Cobalt(II) Octaethylporphyrin
Balch, Alan L.,Mazzanti, Marinella,Olmstead, Marilyn M.
, p. 269 - 270 (1994)
Conditions are reported which allow octaethylporphyrin cobalt(II) to be oxygenated to form the verdoheme analogue, octaethyloxaporphyrincobalt(III) dichloride, which has been isolated and characterized by X-ray diffraction.
