Carboxylation of olefins/alkynes with CO2 to industrially relevant acrylic acid derivatives

▶ Important roles of acrylic acid and derivatives in industries are analyzed. ▶ Carboxylation of unsaturated hydrocarbons with CO2 performs well in the presence of nickel(0) catalysts. ▶ Reactions of alkenylboronic esters and CO2 are promoted by transition metal catalysts. ▶ Carboxylation of alkynes with CO2 proceeds successfully through hydrometalation strategy. ▶ Potential application of CO2 capture and its utilization (CCU) is well discussed.

Carbon dioxide utilization has continued to capture the interest of chemists worldwide due to global warming associated with positive carbon accumulation. As an environmentally friendly C1 feedstock, the reaction of carbon dioxide has been extensively investigated for several decades. On the other hand, acrylic acid is a valuable industrial product that is widely used for various important purposes in industry. From the point view of atom- and process-economical chemistry, the most concise and promising route for acrylic acid derivatives synthesis would be direct carboxylation of olefins or alkynes with carbon dioxide. In this review, we would like to discuss and update the latest advances on synthesis of acrylic acid derivatives from unsaturated hydrocarbons and carbon dioxide.
