Recent Advances in Electrocarboxylation with CO₂

Abstract

Carbon dioxide (CO2) is an abundant, inexpensive, renewable C1 resource and the main component of greenhouse gas, thereby the research for its sustainable and efficient conversion has received notable attention in recent years. Electrochemical organic synthesis, as a green and efficient synthetic method, is convinced to be an ideal approach for CO2 utilization. In this review, recent advances in electrocarboxylation with CO2 were summarized through different reaction types, which would disclose the great potential of electrocarboxylation in green organic synthesis.

Multicomponent catalyst design for CO2/N2/NOxelectroreduction

“…Recently, electrochemical synthesis of carboxylic acid, carbonate, urea, amine, and other organic chemicals from the electroreduction of small molecules was reported, but these reactions are still in the start stage. [61][62][63][64][65][66][67] Multicomponent catalysts have the advantages of producing C-/N-containing intermediates simultaneously and promoting the C-N coupling. 68 Hence, more attention should be paid to developing new routes for electrochemical synthesis using multicomponent catalysts.…”

A guide to organic electroreduction using sacrificial anodes

“…The electrochemical carboxylation with a sacrificial anode is an efficient method for the preparation of carboxylic acid derivatives. 45,46 As shown in Fig. 4, magnesium serves as the dominate anode material in this area, as presumably the in situ formed Mg carboxylates could prevent the undesired Kolbe reaction.…”

Recent advances in the electrochemically mediated chemical transformation of carbon dioxide

“…Transition metal-catalyzed, 5 photoredox 6 and electro-catalytic carboxylations 7 have been proved to be effective and robust methods to synthesize a variety of functionalized carboxylic acids and their derivatives. However, transition metal-catalyzed carboxylation often requires stoichiometric reductants such as Mn/Zn to promote the catalytic cycle, while photocatalysis requires expensive photosensitizers.…”
