Synthesis of α, β-Unsaturated Carboxylic Acids by Nickel(II)-Catalyzed Electrochemical Carboxylation of Vinyl Bromides
Electrochemical carboxylation of alkyl-substituted vinyl bromides (<B>1a</B>-<B>1g</B>) in the presence of 20 mol% of NiBr<SUB>2</SUB>•bpy under an atmospheric pressure of carbon dioxide with a platinum cathode and a magnesium anode gave the corresponding α,β-unsaturated carboxylic acids (<B>2a</B>-<B>2g</B>) in yields of 53-82%.
