Abstract / Full Text

Electrochemical reduction of organohalogen compounds involving a double mediator system ofmetal ions and organic electron carrier is studied. The catalytic action of Ni(II), Co(II), Pd(II), Pt(II), andRh(III) ions on the kinetics of homogeneous reduction of aliphatic, alicylic, and aromatic bromo- and chloro-organic compounds by radical-anions of organic compounds in aprotic media containing tetraalkylammoniumsalts as supporting electrolytes is found. In all cases, there is a synergistic effect increasing with the increase inconcentration of metal ions and with the decrease in the efficiency of organic carrier. By the example of binarymediator reduction involving Ni(II) and Co(II) ions, the reaction is shown to be of the second order by metalions.
