“…Therefore, 2 may undergo further two-electron transfer to the corresponding carbon anion 8, which would react with another CO 2 to form decarboxylation product 4. Given that a small amount of water is still present in the solvent, the protonation process competes with carboxylation [13,58,59]. Then, dehalogenated monocarboxylation product 3 is formed by either carboxylation following protonation or protonation following carboxylation.…”

“…However, CO 2 conversion is a challenge to chemists because of the high chemical and thermodynamic stability of this gas. Electrochemical techniques [10] that deal with a clean reagent, the electron, can realize CO 2 activation at normal temperature and pressure [11][12][13]. Therefore, electrocarboxylation is a facile method of CO 2 fixation from ecological and economic viewpoints.…”

“…Therefore, electrocarboxylation is a facile method of CO 2 fixation from ecological and economic viewpoints. Many substrate types, alcohols [14], epoxides [15,16], imines [17], organic halides [13,[18][19][20][21][22][23][24][25][26][27][28], ketones [11,12,[29][30][31][32], aldehydes [33], alkenes [34][35][36][37][38], and alkynes [39] have been used in previous studies.…”

“…However, Hg is discarded for environmental reasons. Meanwhile, studies have indicated that silver (Ag) exhibits extraordinary electrocatalytic activities toward the reduction of organic halides [13,[18][19][20][21][22][23]43,44]. Although many studies have investigated electroreduction and electrocarboxylation of organic chlorides, most of them focused on monochloride compounds [19,21,22,[40][41][42][43][44].…”

Carbon dioxide (CO 2 ) is the largest contributor to the greenhouse effect, and fixing and using this greenhouse gas in a facile manner is crucial. This work investigates the electrocarboxylation of dichlorobenzenes with the atmospheric pressure of CO 2 in an undivided cell with an Ag cathode and an Mg sacrificial anode. The corresponding carboxylic acids and their derivatives, which are important industrial and fine chemicals, are obtained. To deeply understand this reaction, we investigate the influence of various reaction conditions, such as supporting electrolyte, current density, electric charge, and reaction temperature, on the electrocarboxylation yield by using 1,4-dichlorobenzene as the model compound. The electrochemical behavior of dichlorobenzenes is studied through cyclic voltammetry. The relation among the distinct electronic effects of dichlorobenzenes, the electrochemical characteristics of their reduction, and the distribution law of target products is also established.

“…A drastic increase in efficiency was obtained by employing sacrificial anodes [116], especially magnesium anodes [117–118]. The cathode material is again of great importance, with silver and platinum giving the highest carboxylation selectivity [119–125]. Redox mediators allow working at a less negative cathodic potential, which results in a better energy efficiency and a more selective CO 2 fixation [128].…”

SummaryThe near-unlimited availability of CO2 has stimulated a growing research effort in creating value-added products from this greenhouse gas. This paper presents the trends on the most important methods used in the electrochemical synthesis of carboxylic acids from carbon dioxide. An overview is given of different substrate groups which form carboxylic acids upon CO2 fixation, including mechanistic considerations. While most work focuses on the electrocarboxylation of substrates with sacrificial anodes, this review considers the possibilities and challenges of implementing other synthetic methodologies. In view of potential industrial application, the choice of reactor setup, electrode type and reaction pathway has a large influence on the sustainability and efficiency of the process.

Sustainable electrosynthesis technologies are rapidly developing stimulated by the drive for sustainable chemical manufacturing and the increasingly accessible renewable electricity prices. The electrochemical utilization of easily available feedstock, such as carbon dioxide (CO2), has attracted significant attention as it can additionally help closing the disrupted carbon cycle. While direct CO2 reduction has benefited from recent advancements in the catalyst, electrolyte and system design, developments in electrochemical coupling of CO2 with organic precursors to yield value‐added chemicals have been lagging behind due to the apparent disconnect between the direct CO2 reduction and the organic electrosynthesis communities. Currently, electrocarboxylation reactions require high operating voltages, show low current densities, limited selectivity towards target products and are associated with low atom economy due to the reliance on sacrificial anode dissolution. Advancing this indirect electrochemical CO2 utilization strategy will enable sustainable synthesis of valuable chemicals including non‐steroidal anti‐inflammatory drugs and precursors for plasticizers and commercially‐relevant polymers—all of which are currently produced with high carbon footprint and low atom economy. This perspective discusses the current state‐of‐the‐art in electroorganic synthesis with CO2 as a one‐carbon synthon and suggests several transferrable strategies from direct CO2 reduction breakthroughs to advance electrocarboxylation and bring it closer to industrial implementation.
