Electrochemical carboxylation with CO₂

Carbon dioxide (CO₂) is a widespread, inexpensive, renewable source of C1 carbon and the main component of greenhouse gases, so studies on its efficient conversion into useful products, corresponding to the principles of sustainable development, have received considerable attention in recent years. Electrochemical organic synthesis, as an environmentally friendly, mild and selective synthetic method, is considered an ideal approach to the CO₂ utilization and its use as a reagent. This review summarizes recent advances in the field of electrocarboxylation involving CO₂ as a precursor in reactions of various types, which reveal the great potential of these transformations in the synthesis of “green” organics, with special attention paid to processes at the late-stage of functionalization of complex molecules, promising in pharmaceutical chemistry.
