Abstract
Electrochemical reduction of organohalogen compounds involving a doubl e mediator system of metal ions and organic electron carrier is studie d. The catalytic action of Ni(II), Co(II), Pd(II), Pt(II), and Rh(III) ions on the kinetics of homogeneous reduction of aliphatic, alicylic, and aromatic bromo- and chloroorganic compounds by radical-anions of organic compounds in aprotic media containing tetraalkylammonium salts as supporting electrolytes is found. In all cases, there is a synergi stic effect increasing with the increase in concentration of metal ion s and with the decrease in the efficiency of organic carrier. By the e xample of binary mediator reduction involving Ni(II) and Co(II) ions, the reaction is shown to be of the second order by metal ions.
