Abstract

Kinetic and DFT results for the carbonate catalysed Co(H₂O)₆²⁺+ H₂O₂ Fenton-like reaction suggest a mechanism involving the formation of a cyclic transient, cyclic-(CO₄)Co^II(OOH)(H₂O)₂⁻ that decomposes into Co^II(H₂O)(OOH)(OH)₂ + CO₃⁻, i.e. no OH. radicals are involved. Plausible biological implications are pointed out.
