Copper–dioxygen reactivity involved in the formation of µ-oxo [(por)FeIII–O–CuIIL]+ heterodinuclear complexes (por = porphyrinate, L = tetradentate ligand), and novel synthesis of square-planar FeII(por) species
Abstract
In the reaction of FeIII(por) species with [LCuI(KMeCN)]+ and O2 to give µ-oxo [(por)FeIII–O–CuIIL]+3(por = porphyrinate, L = tetradentate ligand), copper–dioxygen adducts or their decomposition products must be present, otherwise [(por)FeIII–OH] or [(por)FeIII–O–FeIII(por)] products appear; a novel synthesis ot square-planar FeII(por) is also described.
