The oxidative sulfonation of benzene with sulfur dioxide was studied in the presence of copper(II) chloride. The relation of the reaction rate to the amount of sulfur dioxide absorbed and the relation of the initial reaction rate to the benzene concentration is shown. With rise in benzene concentration, the initial reaction rate rose linearly and the amount of SO/sub 2/ absorbed remained practically constant. A mechanism was proposed that included the stage of the successive formation of an intermediate containing Cu(II) with benzene and sulfur dioxide and its subsequent redox breakdown to the final products as a result of attack by a Cu(II) benzene complex.
