Polyaminocarboxylates iron complexes

Extensive efforts have been made to establish and rationalize the kinetics of dioxygen oxidation of iron(II) polyaminocarboxylate complexesThe kinetics of dioxygen oxidation of iron(II) complexes of 1,2- and of 1,3-propylenetetraacetate show the influence of steric factors on these electron transfer reactions7 " ... 

Reactions of iron-polyaminocarboxylates with nitric oxide have already been covered, in Section 5.4.3.8 bi- and polynuclear complexes containing polyaminocarboxylate ligands will be found in Section 5.4.5.4 below. 

Three further papers have appeared on the reaction of polyaminocarboxyl-ato-iron(III) complexes with cyanide. In all cases the reaction sequence involves a final redox step, in which liberated ligand reduces intermediate cyano-iron(III) species to hexacyanoferrate(II). The ligands involved are N-(2-hydroxyethyl)iminodiacetate, triethylenetetraminehexaacetate, and 2-hydroxytrimethylenediaminetetraacetate both in mononuclear and in binuclear complexes.
