1. A method, comprising:

  • (i) contacting an anode with an anode electrolyte wherein the anode electrolyte comprises metal halide and saltwater;

    contacting a cathode with a cathode electrolyte;

    applying a voltage to the anode and the cathode and oxidizing the metal halide with metal ion in a lower oxidation state to a higher oxidation state at the anode;

    (ii) halogenating an unsaturated hydrocarbon or a saturated hydrocarbon with the metal halide with the metal ion in the higher oxidation state in the saltwater to result in one or more organic compounds or enantiomers thereof and the metal halide with the metal ion in the lower oxidation state; and

    (iii) oxyhalogenating the metal halide with the metal ion in the lower oxidation state to the higher oxidation state in presence of an oxidantwherein the step (i) is in series with the step (iii).
