N2 - The kinetics and the reaction mechanism of copper(I) complexes of 5-methyl-1, 10-phenanthroline, 5-chloro-1, 10-phenanthroline, 5-nitro-1, 10-phenanthroline, 2, 9-dimethyl-1, 10-phenanthroline, and 2, 2’-bipyridyl with oxygen and hydrogen peroxide have been investigated in aqueous solutions with use of the pulse radiolysis technique. The oxidation by 02is second order in the copper(I) complex, while the oxidation by H202is first order in the copper(I) complex. Both reactions are first order in oxidants. The kinetic results of the oxidation of copper(I) complexes by oxygen are interpreted by a mechanism that proceeds via a superoxide intermediate.
