Intermediates in reactions of the diimine complex trisferrozineiron(II) with hydroxide or cyanide in binary aqueous solvent mixtures and in micelles

Summary Kinetic and spectroscopic observations are reported for the reaction of tris-ferrozineiron(II) with hydroxide in DMSO- and DMF-H₂O mixtures and with cyanide in MeOH- and DMSO-H₂O mixtures. Micellar effects (CTAB) are described for the reactions of tris-ferrozineiron(II) and of tris-5-sulphonato-1,-10-phenanthrolineiron(II) with hydroxide. Results for the ferrozine complex are discussed in terms of mechanisms involving intermediates formed by attack of hydroxide or cyanide at the coordinated ligand.
