Summary: Here, a methodology for accessing isotopically labeled esters and amides from carbonates and carbamates utilizing an oxygen deletion strategy is reported. The methodology employs a decarboxylative carbonylation approach using C-12 or C-13 carbon monoxide generated ex situ in near stoichiometric amounts for isotope labeling. The reaction demonstrates a broad scope, functional group tolerance, and high yields, exemplified by the synthesis of structurally complex molecules. Additionally, a complementary method for the catalytic in situ generation of CO from CO2 liberated during decarboxylation is developed as a proof-of-concept approach for converting CO2-derived compounds to CO-containing frameworks. Mechanistic studies provide insights into the catalytic steps and the impact of ligand choice for overcoming challenges in low-pressure carbonylation methodologies, aiding the development of future methodologies.

Summary: The covalent attachment of 3- or 4-hydroxy benzene to the 1,3-dimethylimidazolium cation results in zwitterions, which can chemisorb and physisorb carbon dioxide in aqueous solutions. These zwitterionic solutions have low enthalpy of absorption, high adsorption capacity, and can be recycled multiple times.

Summary: In this study, the authors successfully transformed unactivated aryl and alkyl (pseudo)halides into carboxylic acids using nickel catalysis and electricity, with atmospheric CO2 as the carbon source. This sustainable and economic strategy features mild conditions, inexpensive catalyst, and a broad substrate scope, avoiding the use of sacrificial electrodes. The reaction mechanism involves oxidative addition of aryl halides to Ni(0) complex, reduction of aryl-Ni(II) adduct to Ni(I) species, and carboxylation with CO2.

Summary: As an important defect, oxygen vacancy (OV) on the surface of transition metal oxides can serve as a catalytic reactive site for various reactions. In this study, a Cu-doped Co3O4 catalyst with abundant surface OV was developed for efficient and quantitative transformations of CO2, primary amines, and propargyl alcohols to oxazolidinones under mild reaction conditions. The presence of Cu species in Cu/Co3O4 enhanced the activation of propargyl alcohol, increased the surface OV concentration for CO2 activation, and improved the surface acidity, leading to the promotion of the rate-determining step in CO2-to-oxazolidinone transformation.

Summary: Treatment of Si(cat(Cl))(2)(MeCN)(2) with TMP or hppH and CO2 forms silicon carbamates. The hapticity at silicon and reactivity of the carbamates are determined by the Lewis base used. Treatment of the carbamates with a Bronsted acid liberates CO2 and reactivates the superacidic behavior.

Summary: Utilizing electrocatalytic reduction of CO2 to synthesize carbamates is an effective method of CO2 utilization. Developing high-performance electrocatalysts can efficiently promote this process for sustainable development. Single-atom catalysts, like the atomically dispersed Cu species on N-doped carbon nanosheet composite material (Cu-N-C), show potential to enhance the reaction process. The Cu-N-C material exhibits superior catalytic performance in synthesizing methyl N-phenylcarbamate, with an optimized yield of 71% at room temperature and normal pressure. It also demonstrates good stability after repeated use and broad applicability to convert various amines into carbamates smoothly.
