Non-innocent redox behavior of CuII-p-dimethylaminophenolate complexes: formation and characterization of the CuI-phenoxyl radical species.

Abstract

Cu complexes with p-dimethylaminophenolate ligands were synthesized by the reaction of CuII ions with the ligands under inert gas atmosphere and characterized. The complexes showed a valence state change from CuII-phenolate to CuI-phenoxyl radical on loss of the coordinated solvent. The CuI-phenoxyl radical species showed the characteristic properties and reactivities.
