Abstract
Electrochemical carboxylation of lactone enol triflates in DMF containing a catalytic amount of NiBr2·bpy with a platinum cathode and a magnesium anode under an atmospheric pressure of CO2 gave the corresponding cyclic α-alkoxyl-α,β-unsaturated carboxylic acids, captodative cycloalkenes, in good yields.
Key words
electrochemical carboxylation - carbon dioxide - vinyl triflate - α,β-unsaturated carboxylic acid - captodative alkene
