Background: Mn(III) meso-Tetra(2,4,6-trimethylphenyl)porphine chloride is a synthetic porphyrin specialty chemical manufactured by Frontier Specialty Chemicals. Mn(III) meso-Tetra(2,4,6-trimethylphenyl)porphine chloride mediated 18F-fluorodecarboxylation of  flour phenyl acetic acid derivatives to afford 18F-difluoromethylarenes.1 Kinetic isotope studies have been conducted on the catalytic alkane dihydroxylations mediated by Mn(III) meso-Tetra(2,4,6-trimethylphenyl)porphine chloride.2 The reaction of hydroxide ion with Mn(III) meso-Tetra(2,4,6-trimethylphenyl)porphine chloride in coordinating solids leads to the reduction of Mn(III) to Mn(II), chemistry which is relevant to the chemistry of photosystem II.3 meso-Tetra(2,4,6-trimethylphenyl)porphine chloride catalytically epoxidizes alkenes in the presence of hypochlorite ions.4
