Kinetics of reactions of ferroins having ionisable substituents

Abstract

Kinetics of acid fission, alkali fission, and peroxydisulphate oxidation of the 5-amino-, 3-sulpho-, 5-sulpho-, and 4,7-dihydroxy-derivatives of the tris-1,10-phenanthrolineiron(II) cation have been studied to obtain data on the effect of pH on the reacting species and activation energies for the reactions. These activation energies are correlated with other physical results for the complexes and their respective ligands both for the four compounds discussed here and for other substituted iron(II)–phenanthroline complexes studied earlier.
