Synthesis of Carboxylic Acid by Electrochemical Fixation of Carbon Dioxide: A Review of Electrochemical Carboxylation from Past to Latest

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.
