Abstract

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