Abstract
The oxidation of methionine by tetrakis(pyridine)silver dichromate in dimethyl sulphoxide leads to the formation of corresponding sulphoxide. The reaction is of first order with respect to tetrakis(pyridine)silver dichromate. Michaelis-Menten type kinetics was observed with respect to methionine. The reaction is catalyzed by hydrogen ions. The hydrogen-ion dependence has the form: kobs = a + b [H+]. The oxidation of methionine was studied in 19 different organic solvents. The solvent effect was analyzed by Kamlet's and Swain's multiparametric equations. Solvent effect indicated the importance of the cation-solvating power of the solvent. A suitable mechanism has also been postulated.
