A complex of cobalamin with an organic peroxide†
Abstract
Aquacobalamin reacts with m-chloroperoxybenzoic acid (MCPBA) to form a Co(III)-peroxo complex, as supported by UV-vis, NMR and resonance Raman spectra complemented by mass spectra and density functional calculations. At high MCPBA concentrations, degradation of cobalamin is observed as previously described.
