An interpretation of gated behavior: kinetic studies of the oxidation and reduction reactions of Bis(2,9-dimethyl-1,10-phenanthroline)copper(I/II) in acetonitrile

The gated behavior of copper(II) and -(I) species was interpreted by assessing the reduction reactions of bis(2,9-dimethyl-1,10-phenanthroline)copper(I/II) in acetonitrile. A consistency was noted between the electron self-exchange rate constants estimated for the Cu(dmp)(sub 2)(super 2+/+) couple and the directly measured value by NMR(5 X 10 cubed kg mol-1 s-1). The electron self-exchange rate constant of Cu(dmp)(sub 2)(super 2+/+) as 1.6 kg mol-1 s-1 from the reduction of Cu(dmp)(sub 2)(super 2+) by Co(bpy)(sub 3)(super 2+) was obtained.
