Description
Catalytic reductions of NO2, ClO3, and BrO3 by aqueous molybdenum-catechol complexes at pH 9 are investigated by electrochemical techniques. Binding of substrate to the molybdenum center occurs
through the unshared electron pair of the substrate central atom.
The molybdenum (V) and - (IV) oxidation states are catalytically
active, while Mo(III) is not. A single mechanism for the reaction
of Mo(V) with all three substrates is proposed, and a rate expression
for this reaction is derived. General features of the Mo (IV) reaction
are describec. Nitrous oxide was identified by gas chromatography
as a product of the Mo(V) - NO2 reaction.
