Abstract
The micelle-catalyzed aquation rates of iron(II) phenanthroline complex Fe(Ph2Phen) 2+3 have been measured in aqueous acetone as solvent in the presence of urea and sodium benzoate as substrates. The variation patterns manifested by the estimated maximum catalytic factors and ko vs [substrate] profiles show that the aquation rates of the complex are inhibited by urea, while they are significantly enhanced by sodium benzoate. These observations have been radionalized by considering the relative micelle bond-breaking capacities of the substrates, the relative strengths of the H-bonds formed by the substrate/OH− headgroups of the micelle and the H2O/OH− headgroups of the micelle pairs.
