The effect of cathode composition on the efficiency of electrocarboxylation of aromatic halides

Abstract The composition of the cathode has a significant effect on the efficiency of electrocarboxylation of aromatic halides which are relatively difficult to reduce in N , N -dimethylformamide. At low temperatures ( 2 , while at stainless steel passivation effects, which are more serious for the bromides and iodides, primarily influence the efficiency. Experiments with added D 2 O provide no evidence for production of aromatic radical intermediates via CO 2 -mediated one-electron reduction of the halides.
