The pseudo-first order kinetics for the substitution reaction of P{h3SnL [L=2-(2,6-dichlorophenyl)aminophenyl acetate] with ethyl iodide have been studied in Ch2Cl2 at 20oC using controlled temperature controlled UV-Visible Spectroscopy. The reaction shows a first order dependence on both reactants. The rates of the reaction have been calculated and approximate rate constants have been determined for the cleavage of tin-phenyl bond. The reaction is believed to proceed through the associative mechanism.
