Abstract

The kinetics of reactions of cobalamin (II) and cobinamide (II) with sulfur dioxide was studied by UV-visible (UV-vis) spectroscopy. Reaction results in oxidation of Co(II) center and involves two aquated SO2 moieties. The final product is suggested to be complex Co(III)-S2O 4•- . The absence of corrin ring modifications during the reactions was proved.
