抄録

Electrochemical reductions of copper (II) complexes with SCN￣, Py and I￣ were studied in dimetylformamide (DMF) containing tetraethylammonium perchlorate. These copper (II) complexes were precipitated in aqueous solutions as a double salt by addition of nitron to a mixture of copper (II) and SCN￣ ions or that of copper (II) and Py. These products were dissolved in DMF. The DMF solutions were studied by polarography and cyclic voltammetry. At the dropping mercury electrode, the polarographic wave corresponding to the reduction of Cu (I) to Cu (O) appeared at rather negative potential, however, the reductiog wave of Cu (II) to Cu (I) was obscured because of oxidation waves of ligands. At the platinum electrode, the quasi-reversible reduction wave of Cu (II) to Cu (I) was observed at a less negative potential in cyclic voltammetry. These facts showed that the Cu (II) complexes are reduced to Cu (I), and thereafter to Cu (0).
