Du, Minchen published the artcileAn efficient and recyclable AgNO3/ionic liquid system catalyzed atmospheric CO2 utilization: Simultaneous synthesis of 2-oxazolidinones and α-hydroxyl ketones, Product Details of C8H14O, the main research area is oxazolidinone hydroxyl ketone preparation green chem; propargyl alc aminoethanol carbon dioxide three component reaction; silver nitrate ethyl methylimidazolium acetate catalyst.

Oxazolidinones I (R = (CH2)2OH, Bn, 4-MeC6H4CH2, etc.) and α-hydroxyl ketones CH3C(O)C(R1)(R2)OH (R1 = Me, Et; R2 = Me, Et, i-Bu, Ph; -R1R2- = -(CH2)5-) are two series of fine chems. that have been generally utilized in biol., pharmaceutical, and synthetic chem. Herein, a AgNO3/ionic liquid (IL) catalytic system was developed for the simultaneous synthesis of these compounds through the atom-economical three-component reactions of propargyl alcs., 2-aminoethanols, and CO2. Notably, this system behaved excellent catalytic activity with the lowermost metal loading of 0.25 mol%. Meanwhile, it is the first reported metal-catalyzed system that could efficiently work under atm. CO2 pressure and be recycled at least five times. Evaluation of the green metrics proved the AgNO3/IL-catalyzed processes to be relatively more sustainable and greener than the other Ag-catalyzed examples. Further mechanistic investigations revealed the derivative active species of N-heterocyclic carbene (NHC) silver complexes and CO2 adducts generated during the process. Subsequently, their reactivity in this reaction was assessed for the first time, which was finally identified as beneficial for the catalytic activity.

Gu, Ai-Ling published the artcileHighly Efficient Conversion of Propargylic Alcohols and Propargylic Amines with CO2 Activated by Noble-Metal-Free Catalyst Cu2O@ZIF-8, Product Details of C8H14O, the main research area is alkylidene cyclic carbonate oxazolidinone preparation; propargylic alc amine carbon dioxide cycloaddition; metalorganic framework ZIF8 encapsulated cuprous oxide nanoparticle preparation catalyst; CO2; Metal-Organic Frameworks; Noble-Metal-Free; Propargylic Alcohols; Propargylic Amines.

The cyclization reactions of propargylic alcs. and propargylic amines with CO2 are important in industrial applications, but it was a great challenge that non-noble-metal catalysts catalyzed both reactions under mild conditions. Herein, the catalyst Cu2O@ZIF-8 was prepared by encapsulating Cu2O nanoparticles into robust ZIF-8, and it can effectively catalyze the cyclization of both propargylic alcs. and propargylic amines with CO2 into valuable α-alkylidene cyclic carbonates and oxazolidinones with turnover numbers (TONs) of 12.1 and 19.6, which can be recycled at least five times. The mechanisms were further uncovered by NMR, FTIR, 13C isotope-labeling experiments and DFT calculations, in which Cu2O and DBU can synergistically activate the C≃C bond and the hydroxy/amino group of substrates. Importantly, it is the first example of a noble-metal-free catalyst that can catalyze both propargylic alcs. and propargylic amines with CO2 simultaneously.

A highly efficient carboxylative cyclization of propargylic alcs. with CO2 under atm. pressure catalyzed by silver (0) nanoparticles decorated reduced graphene oxide (Ag-rGO) is reported. Ag-rGO was fully characterized by scanning electron microscope spectra (SEM), transmission electron microscopy (TEM), Fourier transform IR (FT-IR) spectra, Raman spectra and XPS. Notably, Ag-rGO can be also applied to the construction of other value-added chems. (β-oxopropylcarbamates and 2-oxazolidinones) from CO2 at ambient conditions. In addition, Ag-rGO is stable and reusable, which shows the potential for the practical application for CO2 capture and utilization (CCU).

Tang, Minhao published the artcileA CO2-mediated base catalysis approach for the hydration of triple bonds in ionic liquids, HPLC of Formula: 107-54-0, the main research area is carbonyl compound preparation green chem; nitrile alkyne hydration carbon dioxide ionic liquid.

Herein, a CO2-mediated base catalysis approach for the activation of triple bonds in ionic liquids (ILs) with anions that can chem. capture CO2 (e.g., azolate, phenolate, and acetate), which can achieve hydration of triple bonds to carbonyl chems. is reported. It is discovered that the anion-complexed CO2 could abstract one proton from proton resources (e.g., IL cation) and transfer it to the CN or CC bonds via a six-membered ring transition state, thus realizing their hydration. In particular, tetrabutylphosphonium 2-hydroxypyridine shows high efficiency for hydration of nitriles and CC bond-containing compounds under a CO2 atmosphere, affording a series of carbonyl compounds in excellent yields. This catalytic protocol is simple, green, and highly efficient and opens a new way to access carbonyl compounds via triple bond hydration under mild and metal-free conditions.

Chen, Mingzhe published the artcileChemical Fixation of CO2 Using Highly Dispersed Cu on Hierarchically Porous N-Doped Carbon, Recommanded Product: 3,5-Dimethylhex-1-yn-3-ol, the main research area is carbon dioxide fixation copper nitrogen doped porous carbon catalyst; oxide carbon fixation copper nitrogen doped porous carbon catalyst; N-doped carbon; carbon dioxide; copper catalyst; coupling reaction; hierarchical porosity.

A heterogeneous catalyst of highly dispersed Cu (Cu/NHPC) supported on hierarchically porous N-doped C (NHPC) can efficiently promote CO2 fixations to oxazolidinones and β-oxopropylcarbamates. The obtained NHPC, assembled by ultrathin N-doped C nanosheets with a 3-dimensional (3D) structure, is readily prepared by pyrolysis of a N-containing polymer gel (NPG) in the presence of an activator of K bicarbonate (KHCO3). The resulting NHPC shows specific Brunauer-Emmet-Teller (BET) surface areas ≤2054 m2 g-1 with a mean micro/mesopore size of 0.55/3.2 nm and a broad macropore size distribution from 50 to 230 nm. The Cu/NHPC can efficiently promote 3-component coupling of CO2, amines, and propargyl alcs. for syntheses of various oxazolidinones and β-oxopropylcarbamates with yields ≤99% and a wide substrate scope. The Cu/NHPC exhibits excellent recyclability in CO2-to-oxazolidinone transformation during 9-time recycling. The research develops an NHPC-based heterogeneous Cu catalyst for green transformation of CO2.
