A green approach for the synthesis of 2-oxazolidinones using gold(I) complex immobilized on KCC-1 as nanocatalyst at room temperature

A novel gold(I)-containing ionic liquid-based KCC-1 catalyst was applied for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. High catalytic activity and ease of recovery from the reaction mixture using an external ma

Cycloaddition of Propargylic Amines and CO2 by Ni@Pd Nanoclusters Confined Within Metal–Organic Framework Cavities in Aqueous Solution

The bio-metal–organic framework (bio-MOF) notion along with nanoparticles catalysts of Ni@Pd core–shell magnetic for carbon dioxide conversion is made by l-glutamic acid that is the natural substitute for combinatorial ligands, and illustrated their catal

Ni@Pd nanoparticles supported on ionic liquid-functionalized KCC-1 as robust and recyclable nanocatalysts for cycloaddition of propargylic amines and CO2

Novel heterogeneous catalyst systems comprised of a fibrous nanosilica-supported nano-Ni@Pd-based ionic liquid (KCC-1/IL/Ni@Pd) are described for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. KCC-1 with high surface area was functionalized with IL acting as a robust anchor so that the nano-Ni@Pd was well dispersed on the fibres of the KCC-1 microspheres, without aggregation. Because of the amplification effect of IL, high loading capacities of the nanocatalysts were achieved. The reported synthesis includes several advantages like solvent-free conditions, operational simplicity, short reaction times, environmentally benign reaction conditions, cost effectiveness, high atom economy and excellent yields, making it a genuinely green protocol.

KCC-1 Supported Ruthenium-Salen-Bridged Ionic Networks as a Reusable Catalyst for the Cycloaddition of Propargylic Amines and CO2

Abstract: This study investigates the potential application of an efficient, easily recoverable and reusable KCC-1 nanoparticle-supported Salen/Ru(II) catalyst in the synthesis of 2-oxazolidinones from CO2, and propargylic amines. The KCC-1/Salen/Ru(II) NPs were thoroughly characterized by using TEM, SEM, TGA, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.

Efficient synthesis of 2-oxazolidinones and quinazoline-2,4(1H,3H)-diones from CO2 catalyzed by tetrabutylammonium fluoride

By employing tetrabutylammonium fluoride (TBAF) as a catalyst, the various carboxylative cyclizations of the propargylic amines having internal alkynes with CO2 proceeded to afford the corresponding 2-oxazolidinones. In this case, it was also found that the generated 2-oxazolidinones were tautomerized into the corresponding 2-oxazolones due to the basicity of TBAF. In addition, we performed the synthesis of quinazoline-2,4(1H,3H)-dione from 2-aminobenzonitrile and CO2 by using TBAF as a catalyst.

Efficient and Reusable Metal–Organic Framework Catalysts for Carboxylative Cyclization of Propargylamines with Carbon Dioxide

Carbon dioxide (CO2) capture and transformation are important for decreasing the concentration of atmospheric CO2. To effectively capture CO2 and further fix it into valuable chemical products, functionalized dynamic metal–organic frameworks (MOFs) have been utilized not only because of their inherent cavity for accommodating CO2 but also owing to their reversible structural transformations in response to external stimuli for regulating the reaction. Herein, we report a dynamic and functional MOF [Cd3(L)2(BDC)3]2?16 DMF (MOF-1 a; DMF=N,N-dimethylformamide) achieved by reaction of the amino tripodal imidazole ligand N1-(4-(1 H-imidazol-1-yl)benzyl)-N1- (2-aminoethyl)ethane-1,2-diamine (L) and 1,4-benzenedicarboxylic acid (H2BDC) with cadmium salt. MOF-1 a not only shows unprecedented high catalytic activity [initial turnover number (TON) up to 9300] and broad substrate scope for the carboxylative cyclization of propargylamines with CO2, but also can be switched on and off upon reversible structural transformation owing to its dynamic five-fold interpenetrating structure. Further studies demonstrate that MOF-1 a shows selective catalytic properties depending on the size of substrates, similarly to sophisticated biological systems.

Gold (III) phosphorus complex immobilized on fibrous nano-silica as a catalyst for the cyclization of propargylic amines with CO2

In this study, The HPG@KCC-1 NP was prepared through the ringopening polymerization of glycidol on the surface of KCC-1 to form HPG@KCC-1 and then HPG@KCC-1 NPs were functionalized using chlorodiphenylphosphine and phosphine-functionalized nanoparticles (HPG@KCC-1/PPh2) as a recyclable phosphorus ligand was obtained. Also, gold (III) complex of HPG@KCC-1/PPh2 ligand (HPG@KCC-1/PPh2/Au) was prepared which used for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. High catalytic activity and ease of recovery from the reaction mixture using filtration, and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system.
