Abstract

The catalytic oxidation of pyrrole by the [(salen)V^IVOV^V(salen)]³⁺ cation, which is formed on an electrode surface by the oxidation of [(salen)V^IVOV^IV(salen)]²⁺, was examined by hydrodynamic voltammetry at a rotating glassy carbon disk electrode. The electron transfer rate constant for the cross-reaction [(salen)VOV(salen)]³⁺/pyrrole was estimated to be 4 × 10⁴ mol^-1 cm³ s^-1. O₂-oxidation of the [(salen)VOV(salen)]⁺ cation gives rise to the catalysis for the O₂-oxidative polymerization of pyrrole. The polymerization was rate-determined by the reoxidation step of the catalyst by O₂.
