Synthesis of the High-valent Mn Porphyrin Species by Peroxy Acid Oxidation of MnIII Dimers. Characterization of the MnIV2 Species and Evidence of the MnV-MnIII Intermediate

Abstract

Abstract The MnIV porphyrin dimers were synthesized and characterized by UV-vis, ESI-MS, etc. Epoxidation of olefins indicated the transient formation of the MnV (=O) species, which were transformed into the MnIV species by the intramolecular comproportionation between MnV-MnIII moieties.
