meso-Tetra(2,6-dichlorophenyl)- and meso-tetra(pentachlorophenyl)porphinatoiron(III) chloride, which resist μ-oxo dimer formation and oxidative destruction, are efficient catalysts for high turnover, high yield epoxidations of alkenes, e.g. norbornene, and hydroxylation of alkanes, e.g. cyclohexane and norbornane.
