Oxidation of the Fe n chelates [FeL l (L = phen or bipy) by Cr w and Mn TM in H2SO 4 medium was found to proceed through the formation of a bimetallic insertion complex which decomposes in the slow step, followed by electron transfer from [FeLl to the oxidant. The reactions are catalysed by both ani
