Synthesis of 2-oxazolidinone by N-heterocyclic carbene-catalyzed carboxylative cyclization of propargylic amine with CO2

By employing N-heterocyclic carbenes as catalysts, the carboxylative cyclization of propargylic amine proceeded under 0.6 MPa of CO2 to afford the corresponding 2-oxazolidinone at 90 °C in 2-propanol. Among N-heterocyclic carbenes, 1,3-di-t-but

Efficient conversion of carbon dioxide at atmospheric pressure to 2-oxazolidinones promoted by bifunctional Cu(ii)-substituted polyoxometalate-based ionic liquids

Copper(ii) substituted polyoxometalate-based ionic liquids e.g. [(nC7H15)4N]6[α-SiW11O39Cu] were successfully developed as halogen-free bifunctional catalysts for the carboxylati

Silver(I)-Catalyzed Synthesis of β-Oxopropylcarbamates from Propargylic Alcohols and CO2 Surrogate: A Gas-Free Process

The utilization of carbon dioxide poses major challenges owing to its high thermodynamic stability and kinetic inertness. To circumvent these problems, a simple reaction system is reported comprising ammonium carbamates as carbon dioxide surrogates, propargylic alcohols, and a silver(I) catalyst, for the effective conversion of a wide range of alcohols and secondary amines into the corresponding β-oxopropylcarbamates. A key feature of this strategy includes quantitative use of a carbon resource with high product yields under gas-free and mild reaction conditions. Notably, this catalytic protocol also works well for the carboxylative cyclization of propargylic amines and carbon dioxide surrogates to afford 2-oxazolidinones.

Carboxylative Cyclization of Propargylic Amines with Carbon Dioxide?- Catalyzed by Poly(amidoamine)-Dendrimer-Encapsulated Gold Nanoparticles

We prepared gold nanoparticles encapsulated in poly(amidoamine) (PAMAM) dendrimers as templating agents. The resulting gold nanoparticles were used as catalysts for the carboxylative cyclization of propargylic amines with carbon dioxide to afford the corr

Energyless CO2 absorption, generation, and fixation using atmospheric CO2

From an economic and ecological perspective, the efficient utilization of atmospheric CO2 as a carbon resource should be a much more important goal than reducing CO2 emissions. However, no strategy to harvest CO2 using atm

Quaternary ammonium salt-catalyzed carboxylative cyclization of propargylic amines with CO2

By employing quaternary ammonium salts as catalysts, the carboxylative cyclization of the propargylic amines with CO2 proceeded to afford the corresponding 2-oxazolidinones. In particular, tetra-n-butylammonium fluoride was the most effective c

Non-Noble-Metal Metal-Organic-Framework-Catalyzed Carboxylative Cyclization of Propargylic Amines with Atmospheric Carbon Dioxide under Ambient Conditions

The coupling reaction of propargylic amines and carbon dioxide (CO2) to synthesize 2-oxazolidinones is an important reaction in industrial production, and yet harsh reaction conditions and noble-metal catalysts are often required to achieve high product yields. Herein, one novel noble-metal-free three-dimensional framework, [Mg3Cu2I2(IN)4(HCOO)2(DEF)4]n (1), assembled by magnesium and copper clusters was synthesized and applied to this reaction. Compound 1 displays excellent solvent stability. Importantly, 1, acting as heterogeneous catalyst, can highly catalyze the cyclization of propargylic amines with CO2 under atmospheric pressure at room temperature, which can be recycled at least five times without an obvious decrease of the catalytic activity. NMR spectroscopy, coupled with 13C-isotope- and deuterium-labeling experiments, clearly clarifies the mechanism of this catalytic system: CO2 was successfully captured and converted to the product of 2-oxazolidinones, the CC bond of propargylic amines can be effectively activated by 1, and proton transfer was involved in the reaction process. Density functional theory calculations are further conducted to uncover the reaction path and the crucial role of compound 1 during the reaction.

PrVO4/SnD NPs as a Nanocatalyst for Carbon Dioxide Fixation to Synthesis Benzimidazoles and 2-Oxazolidinones

Recently CO2 stabilization has received a great deal of attention because of its probable applications as a rich C1 resource and the synthesis of several fine chemicals can be accomplished through this stabilization. In this study, Sn(IV) doping dendritic fibrous nanosilica (SnD) supported PrVO4 nanoparticles as a catalyst (PrVO4/SnD) was synthesized by a in-situ procedure. The SnD with the ratios of Si/Sn in a variety of 6 to 40 were acquired through direct hydrothermal synthesis (DHS), and PrVO4 NPs on the surfaces of SnD were reduced in-situ. X-Ray diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and X-ray energy dispersive spectroscopy (EDS) were deployed for identifying the PrVO4/SnD. It is potentially a highly dynamic catalyst in the stabilization of CO2 for the production of 2-oxazolidinones and benzimidazoles. In addition, the catalyst is very easy to recycle and reuse without significant loss of active site Cu metal.
