processes and the paramagnetic relaxation involving the mixed ligand copper(II)-bipyridyl-glycine complex have been determined by measuring the T 2 relaxation time of the water protons. It was found that the kinetic activity of the CubipyG + mixedcomplex against the ligand exchange process is not significantly different from that of the CuG 2 parent complex. An extremely high rate constant was found for the

Abstract The mechanism of the autoxidation of ferrocytochrome c catalysed by some copper(II) complexes has been estblished. In most cases the rate determining step was found to be the one electron oxidation of the cytochrome by the copper(II) species, which was followed by the rapid reoxidation of the resulting Cu(I) complexes by molecular oxygen. The rate constants for the electron transfer reactions
