Abstract

Abstract: The second-order rate constants (k,,) for reactions of [meso-tetrakis (2, 6-dimethyl-3- sulfonatophenyl)~ rphina-tolmanganese (II1) hydrate [(1) Mn111 (X) 2, X= H20 or HO-] with t- BuOOH and (Ph)(Me), COOH have been determined in aqueous solution in the pH range 7.3-12.6. The pH dependencies of kl, were fitted to a kinetic expression (eq 2) that was similar to that shown previously to describe the pH dependence of the reaction of (1) ...
