To probe whether O3 can function as an oxygen-atom transfer agent in aqueous solution the reaction of NH4[(dipic)V(O)2], dipic = 2,6-pyridinedicarboxylate, with O3 is studied in buffered aqueous solutions at pH 4, 7 and 10. The UV-Vis spectrum of the solution at the end of the ozonization is different at the different pHs. These changes are compared to known high-valent vanadium dipic complexes at the same pH to identify the products of the ozonization. Possible reaction pathways to the observed products will be discussed.
