Abstract

Electrochemical reduction of organic compounds in the presence of carbon dioxide results in the fixation of carbon dioxide into the substrates with carbon-carbon bond forming reaction to yield the corresponding carboxylic acids. The reaction is called “electrochemical carboxylation” or “electrocarboxylation”. Various kinds of carboxylic acids have been synthesized using carbon dioxide as a carboxyl group source by electrochemical carboxylation. In this mini-review, several representative kinds of carboxylic acids synthesized from carbon dioxide by electrochemical carboxylation are briefly summarized/introduced, comparing past and latest.

Keywords: Electrochemical carboxylation, fixation of carbon dioxide, carboxylic acids, sacrificial anode, electroorganic synthesis, amino acids, undivided cell, carbon-carbon bond forming reaction.
