The photocatalytic formation of a non-heme oxoiron(IV) complex, [(N4Py)FeIV(O)]2+ [N4Py = N,N-bis(2-pyridylmethyl)-N- bis(2-pyridyl)methylamine], efficiently proceeds via electron transfer from the excited state of a ruthenium complex, [RuII(bpy)3] 2+* (bpy = 2,2′-bipyridine) to [CoIII(NH 3)5Cl]2+ and stepwise electron-transfer oxidation of [(N4Py)FeII]2+ with 2 equiv of [Ru III(bpy)3]3+ and H2O as an oxygen source. The oxoiron(IV) complex was independently generated by both chemical oxidation of [(N4Py)FeII]2+ with [RuIII(bpy) 3]3+ and electrochemical oxidation of [(N4Py)Fe II]2+.
