Aqueous solutions of copper(II) are reduced in the presence of copper metal and the olefinic ligand, allyl alcohol, to copper(I). The rate of reduction was followed by the titrimetric determination of copper(I) with EDTA and also by the spectrophotometric determination of copper(I) with 2,9-dimethyl-1,10-phenanthroline. The rate of reduction is dependent on the pH of the solution and on the concentration of sulfate ions in solution; the rate of reduction is independent of the concentration of copper(I) species in solution. The kinetic data suggest that the rate of the reduction process is controlled by a reversible electron-transfer reaction between copper(II) ions in solution and the copper metal surface and an irreversible complexation of copper(I) with allyl alcohol. The activation energy for the reduction process is 20 kJ.
