ABSTRACT

Through electrochemical oxidation benzaldoximes can be readily converted to the corresponding benzaldehydes in biphasic medium. Biphasic electrolysis has a distinct advantage over conventional homogeneous electrolysis in synthesis. The electrochemical oxidation resulted in the high yield of benzaldehyde (87%). The reaction was carried out with platinum electrodes at room temperature in an undivided cell within constant biphasic medium consisting of chloroform containing benzaldoxime and an aqueous solution of various perchlorate salts as the mediators with a catalytic amount of H2SO4.
