Abstract
The mechanisms of the reactions which may take place in the oxidation of tetraazamacrocyclic complexes of the transition metals are discussed. It is noted that as a result of oxidation both complexes of metal ions in higher oxidation states with the initial ligands and complexes of the radical cation without a change in the oxidation state of the central ion may be formed. “Cascade oxidation” reactions of macrocyclic ligands are discussed, which seem to take place in oscillating chemical reactions involving the tetraazamacrocyclic complexes of nickel and copper. The possibilities of stabilizing unusual oxidation states of metal ions in a tetraazamacrocyclic environment are considered.
