Production of a putative iron (V) - Oxocorrole species by photo-disproportionation of a bis-corrole - Diiron(IV) - μ-oxo dimer: Implication for a green oxidation catalyst

Photodisproportionation of a bis-corrole-diiron(IV)-μ-oxo dimer gave a corrole-iron(III) species and a corrole-iron (V)-oxo species that can be detected and studied in real time. Air oxidation of the corrole-iron(III) species regenerated the bis-corrole-diiron(IV)-μ-oxo dimer, allowing the development of a photocatalytic method for organic oxidations using molecular oxygen and visible light.

Photochemical generation of a highly reactive iron-oxo intermediate. A true iron(v)-oxo species?

Laser flash photolysis of 5,10,15-tris(pentafluorophenyl)corrole-iron(IV) chlorate or nitrate, prepared from the corresponding chloride, gave a highly reactive iron-oxo transient identified as an iron(V)-oxo species on the basis of its UV-visible spectrum and high reactivity as well as by analogy to photochemical ligand cleavage reactions of related manganese species. The transient was shown to be an oxo transfer agent in a preparative reaction with cis-cyclooctene. Representative rate constants for oxidation reactions by the new transient at ambient temperature were k = 5900 M-1 s-1 for cyclooctene and k = 570 M-1 s-1 for ethylbenzene. The new transient is more than 6 orders of magnitude more reactive with typical organic reductants than expected for an iron(IV)-oxo corrole radical cation and 100 times more reactive than an analogous positively charged iron(IV)-oxo porphyrin radical cation. Slow electron transfer isomerization of ligand iron(V)-oxo species to iron(IV)-oxo ligand radical cations might be important in reactions of porphyrin-iron catalysts in the laboratory and in nature.
