Reaction of tris(4,7-diphenyl-1,10-phenanthrolinedisulphonato)iron(II) ion with hydroxide ion is strongly accelerated by cationic micellar systems. Kinetics both in water and in cationic micelles are consistent with a mechanism of consecuive reactions with a reversible step, and the rate constants have been determined. Results in micelles are explained in terms of thepseudo-phase ion-exchange and mass-action kinetics models, and they show that micelles speed the reaction by an authentic catalytic effect by stabilization of transition state of the reaction.
