AbstractThe reaction of dioxygen with a series of para-substituted meso-tetraphenylporphinatomanganese (II) complexes, MnII(T (p-x) PP) (nBuNH2) where x = H, CH3, Cl, OCH3 in chloroform was studied. Oxidation rate constants were determined at room temperature using spectrophotometric methods. Fitting the observed values for the autoxidation rate constants to the Hammett equation (logkb vs 4 σ) gave a Hammett pb value of -0.280. The effect of substitutents upon the pseudo-first-order rate constants is discussed. In comparison, the half-wave potentials (E1/2) for the metal centred redox reaction, [(MnII(T(p-x)PP) (BuNH2)] ⇋ [MnIII(T(p-x)PP) (BuNH2)]+ + e, were investigated by cyclic voltammetry. A relationship between E1/2 and the Hammett constants was found.
