“…Inoue et al coupled CdS (photocatalyst) to methyl viologen (electron mediator) and isocitrate dehydrogenase (reaction catalyst) to fix CO 2 in oxoglutaric acid 3b to produce isocitric acid 4b (R = -CH 2 CO 2 H, Scheme 3). 32 Inoue et al also developed a system based on TiO 2 and CdS coupled to MV and malic enzyme to convert lactic acid 2 to malic acid 4a via pyruvic acid 3a (R = H, Scheme 3). 34 Lactic acid acted as the hole scavenger and was oxidized to pyruvic acid, which subsequently was carboxylated by malic enzyme to afford malic acid.…”

“…For example, several series reactions of three enzymes (formate dehydrogenase, aldehyde dehydrogenase, and alcohol dehydrogenase) have been applied in CO 2 fixation into methanol. 19) Isocitrate dehydrogenase 20,21) and malic enzyme 3) can also be applied in carboxylation. However, in these cases, CO 2 fixed from 0.007-1.1 mM of the products.…”

Malic enzyme [L-malate: NAD(P)(+) oxidoreductase (EC 1.1.1.39)] catalyzes the oxidative decarboxylation of L-malic acid to produce pyruvic acid using the oxidized form of NAD(P) (NAD(P)(+)). We used a reverse reaction of the malic enzyme of Pseudomonas diminuta IFO 13182 for HCO(3)(-) fixation into pyruvic acid to produce L-malic acid with coenzyme (NADH) generation. Glucose-6-phosphate dehydrogenase (EC1.1.1.49) of Leuconostoc mesenteroides was suitable for coenzyme regeneration. Optimum conditions for the carboxylation of pyruvic acid were examined, including pyruvic acid, NAD(+), and both malic enzyme and glucose-6-phosphate dehydrogenase concentrations. Under optimal conditions, the ratio of HCO(3)(-) and pyruvic acid to malic acid was about 38% after 24 h of incubation at 30 degrees C, and the concentration of the accumulated L-malic acid in the reaction mixture was 38 mM. The malic enzyme reverse reaction was also carried out by the conjugated redox enzyme reaction with water-soluble polymer-bound NAD(+).

“…The energetic stability of the carbon dioxide molecule (DG8 = À394 kJ mol À1 ), however, constitutes a strong limitation to CO 2 reduction and makes this reaction highly endoergic. [25] The basic concept of photocatalytic carboxylation is CÀC bond formation upon the coupling of two radicals: an organic one and CO 2 C À . [18][19][20][21] They include cistrans isomerisation, substitution and cycloaddition processes.…”

Photocatalytic Carboxylation of Organic Substrates with Carbon Dioxide at Zinc Sulfide with Deposited Ruthenium Nanoparticles

Photocatalytic carboxylation of acetylacetone with carbon dioxide has been performed by using ZnS‐based photocatalysts. The formation of two isomeric carboxylic acids, as proven by IR and 13C NMR spectroscopy, was observed. The reaction yield was enhanced after deposition of ruthenium nanoparticles on ZnS. The reaction encompasses ruthenium‐mediated one‐electron reduction of CO2 to CO2.− with electrons from the conduction band of ZnS and one‐hole oxidation of acetylacetone to the relevant radical. Coupling of photogenerated radicals leads to the formation of carboxylic acids. Generation of CO2.− has been confirmed by spin‐trapping EPR measurements. The process described herein may find applications for the solar‐light‐driven green synthesis of Cn+1 carboxylic compounds from Cn substrates by utilising carbon dioxide.
