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.

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.

Li, Jing-Yuan published the artcileCascade Strategy for Atmospheric Pressure CO2 Fixation to Cyclic Carbonates via Silver Sulfadiazine and Et4NBr Synergistic Catalysis, Application of 3,5-Dimethylhex-1-yn-3-ol, the main research area is cyclic carbonate preparation; hydroxyketone preparation; carbon dioxide diol propargyl alc cascade fixation synergistic catalyst.

It is of great significance and challenge for highly efficient catalytic transformation of carbon dioxide into cyclic carbonates especially under low pressure and energy input conditions. In this regard, an efficient silver sulfadiazine/Et4NBr synergistic catalytic system was developed for the three-component cascade reaction of propargylic alcs., CO2, and vicinal diols. The reaction was performed in the absence of any solvent under atm. CO2 pressure to afford splendid yields of cyclic carbonates. The excellent performance was ascribed to the simultaneous activation of hydroxyl group in propargylic alcs./vicinal diols by silver sulfadiazine and synergistic effect between silver species and bulkier Et4N+ in the procedure of intramol. nucleophilic cyclization confirmed by control experiments and NMR spectra.

Das, Rajesh published the artcileHighly Efficient Fixation of Carbon Dioxide at RT and Atmospheric Pressure Conditions: Influence of Polar Functionality on Selective Capture and Conversion of CO2, COA of Formula: C8H14O, the main research area is carbon dioxide fixation room temperature polar functionality influence; oxazolidione preparation cyclic carboxylation alkyne porous MOF catalyst.

The rapid increase in the concentration of atm. carbon dioxide (CO2) has resulted in undesirable environmental issues. Hence, selective CO2 capture and utilization as C1 feedstock for the preparation of high-value chems. and fuels has been considered as a promising step toward mitigating the growing concentration of atm. CO2. In this direction, herein we report rational construction of a Ag(I)-anchored sulfonate-functionalized UiO-66 MOF named as MOF-SO3Ag composed of CO2-philic sulfonate functionality and catalytically active alkynophilic Ag(I) sites for chem. fixation of carbon dioxide. The MOF-SO3Ag exhibits selective as well as recyclable adsorption of CO2 with a high heat of adsorption energy (Qst) of 37.8 kJ/mol. On the other hand, the analogous MOF, UiO-66 doped with Ag(I), showed a lower Qst value of 30 kJ/mol, highlighting the importance of the sulfonate group for stronger interaction with CO2. Furthermore, the MOF-SO3Ag acts as an efficient heterogeneous catalyst for cyclic carboxylation of propargylic alcs. to generate α-alkylidene cyclic carbonates in >99% yield at mild conditions of RT and 1 bar CO2. More importantly, one-pot synthesis of oxazolidinones by a three-component reaction between CO2, propargylic alc., and primary amine has also been achieved using MOF-SO3Ag catalyst under the mild conditions. The MOF is highly recyclable and retains its superior catalytic activity even after several cycles. To the best of our knowledge, MOF-SO3Ag is the first example of MOF reported for RT chem. fixation of CO2 to oxazolidinones by aminolysis of α-alkylidene cyclic carbonates under the environment-friendly mild conditions. An efficient chem. fixation of CO2 into high-value chems., α-alkylidene cyclic carbonates, and oxazolidinones by cyclic carboxylation of alkyne mols. with CO2 catalyzed by Ag(I) anchored porous MOF under environment-friendly mild conditions of RT and atm. pressure of CO2 is presented. This work demonstrates the potential application of porous MOFs with pores functionalized with polar functionality for selective carbon capture and utilization (CCU) for synthesis of high-value chems.

Addnl., catalytic explorations reveal that 1 displays higher catalytic activity than 2 for the carboxylic cyclization of propargyl alcs. More importantly, 1 also exhibits excellent catalytic performance in the carboxylation reactions of CO2 and terminal propargylic alcs. with various substituents. To the best of authors knowledge, this is the first example of non-noble metal based MOF catalysts for the carboxylative cyclization of propargyl alcs. with CO2 under atm. pressure and at room temperature, which provides a highly promising approach for MOFs in the catalytic conversion of CO2 to valuable chems.

Hou, Sheng-Li published the artcileA Noble-Metal-Free Metal-Organic Framework (MOF) Catalyst for the Highly Efficient Conversion of CO2 with Propargylic Alcohols, Recommanded Product: 3,5-Dimethylhex-1-yn-3-ol, the main research area is MOF catalyst carbon dioxide propargylic alc cyclization; copper iodide indium aminonicotinic acid MOF catalyst; carbon dioxide fixation; cyclizations; heterogeneous catalysis; metal-organic frameworks (MOFs); noble-metal-free.

Cyclization of propargylic alcs. with CO2 is an important reaction in industry, and noble-metal catalysts are often employed to ensure the high product yields under environmentally friendly conditions. Herein a porous noble-metal-free framework {(NH2C2H6)0.75[Cu4I4·(L)3·(In)0.75]·DMF·H2O} (L- 5-aminonicotinic acid) with large 1D channels of 1.66 nm diameter was synthesized for this reaction. Compound {(NH2C2H6)0.75[Cu4I4·(L)3·(In)0.75]·DMF·H2O} exhibits excellent acid/base stability, and is even stable in corrosive triethylamine for one month. Catalytic studies indicate that {(NH2C2H6)0.75[Cu4I4·(L)3·(In)0.75]·DMF·H2O} is an effective catalyst for the cyclization of propargylic alcs. and CO2 without any solvents under mild conditions, and the turnover number (TON) can reach to a record value of 14,400. Furthermore, this MOF catalyst also has rarely seen catalytic activity when the biol. macromol. ethisterone was used as a substrate. Mechanistic studies reveal that the synergistic catalytic effect between CuI and InIII plays a key role in the conversion of CO2.

Zhang, Yongxing published the artcileCO2-induced dissolution of ZnO into ionic liquids and its catalytic application for the hydration of propargylic alcohols, SDS of cas: 107-54-0, the main research area is propargylic alc ionic liquid zinc catalyst hydration green chem; hydroxyketone preparation.

An unexpected CO2-induced dissolution of ZnO into ionic liquids was discovered. This process exhibited high dissolution speed and the dissociated mixture was applied as an efficient Zn-based catalytic system for the CO2-promoted hydration of propargylic alcs. under atm. pressure with broad substrate scope. Moreover, this system was recycled and reused for at least 16 times with excellent yields continuously obtained, which was an unprecedented record for this reaction. Significantly, this system could employ waste pigments as the ZnO source and work even under flue gas atm. In the mechanistic investigations, the interaction between ZnO, CO2 and ionic liquids to give N-heterocyclic carbene/CO2 adducts proved to be the key factor for this specific dissolution These adducts were further identified to exhibit better reactivity than the normal CO2 by exptl. data and d. functional theory (DFT) calculations, which might be responsible for the excellent performance of the abovementioned catalytic system.
