Quinone-functionalized chelating ligands may be used to effect sequential electron/proton transfer steps necessary for the reduction of substrate molecules coordinated to a complexed metal ion. The chelating ligand (NQ)[sub 2]en has been synthesized by condensing 2 equiv of 2-hydroxy-3-acetyl-1,4-naphthoquinone with ethylenediamine. Complexes of Cu(II) and Ni(II) have been prepared and characterized. Electrochemical properties of the complexes show that, in the fully reduced bis(hydroquinone) form, the ligand would be able to provide four electrons and protons to a coordinated substrate molecule at strongly negative potentials. 8 refs., 2 figs.
