Summary

The oxidation ofDL-methionine (MT) bybis(2,2′-bipyridyl)copper(II) permanganate (BBCP) to the corresponding sulphoxide is first order in BBCP. Michaelis-Menten-type kinetics were observed with respect to MT. The formation constant of the intermediate complex and the rate constant for its decomposition were evaluated. The thermodynamic and activation parameters were also evaluated. The reaction is catalysed by H+ but 2,2′-bipyridine does not affect the reaction rate. A mechanism is proposed.
