Kinetic study on the Oxidation of Dibenzyl Sulfide with iron(III) polypyridyl complexes in the presence of Cationic micelle

Abstract

The kinetics of the reaction between DBS with Fe(NN) 3 ] 3+ was followed spectrophotometrically by measuring the increase in absorbance of [Fe(NN) 3 ] 2+ with time. The article describes a detailed kinetic investigation on the oxidation of DBS by iron(III)polypyridyl complexes in the presence of CTAB, cationic micelle. The kinetics in miceller medium is governed by both electrostatic interactions and hydrophobic between micelles and reactants, transition states and product 1-4. The increase in rate with increase in [CTAB] demonstrates the importance of hydrophobic interactions in the binding of positively charged metal complexes to micelles.
