Synthesis of α,β-unsaturated carboxylic acids by nickel(II)-catalyzed electrochemical carboxylation of vinyl bromides

Article abstract of DOI:10.1246/cl.1997.917

Electrochemical carboxylation of alkyl-substituted vinyl bromides (1a-1g) in the presence of 20 mol% of NiBr₂?bpy under an atmospheric pressure of carbon dioxide with a platinum cathode and a magnesium anode gave the corresponding α,β-unsaturated carboxylic acids (2a-2g) in yields of 53-82%.
