The metallopolymer cobalt(II) complex of a simple pyridine- and amide-containing copolymer (Co^II-P₉) was prepared and characterized with IR and ¹H NMR.  The ¹H NMR spectrum of the copolymer indicates that the average repeating unit of the copolymer P₉ is vinyl pyridine:acrylamide = 5:1.  The IR spectra suggest that cobalt is bound to the polymer through the pyridine nitrogen atom and the acrylamide does not participate in the binding.  The oxidation of catechol by Co^II-P₉ in the presence of 7.5 mM H₂O₂ exhibits enzyme-like pre-equilibrium kinetics, yielding k_cat = 0.026 ± 0.3 s^–1, dissociation constant K′ = 1.9 ± 0.6 mM, and k_cat /K′ = 13.7 M^–1s^–1.  The inert 4,5-dichlorocatechol is also oxidized by Co^II-P₉ in absence of H₂O₂ to afford rate constants of k_cat = (3.1 ± 0.2) × 10^–4 s^–1 and K′  = 0.7 ± 0.1 mM. This study has introduced a simple catalase-like system to explore the mechanism of Co(II)-centered redox chemistry and its application.
