 Dicarboxylic acids are attractive structures in organic synthesis and are found in many bioactive compounds. They can be produced by reacting carbon dioxide with other compounds, making them useful in the polymer industry. This process, known as dicharboxylation, has been developed to convert carbon dioxide into valuable materials. It is also a potential solution for capturing and using carbon dioxide. Recent research has focused on developing new methods for dicharboxylation, including electrochemical, photochemical, and catalytic processes. These methods have improved the efficiency and selectivity of the reaction, allowing for more efficient production of dicharboxylic acids from carbon dioxide.
