Interfacial Frustrated Lewis Pairs of CeO2 Activate CO2 for Selective Tandem Transformation of Olefins and CO2 into Cyclic Carbonates

Effective activation of CO2 is a prerequisite for efficient utilization of CO2 in organic synthesis. Precisely controlling the interfacial events of solids shows potential for activation. Herein, defect-enriched CeO2 with constructed interfacial frustrated Lewis pairs (FLPs, two adjacent Ce3+···O2-) effectively activates CO2 via the interactions between C/Lewis basic lattice O2- and the two O atoms in CO2/two adjacent Lewis acidic Ce3+ ions. Selective cyclic carbonate production from a catalytically tandem protocol of olefins and CO2 is used to demonstrate FLP-inspired CO2 activation.

A new class of organoplatinum-based DFNS for the production of cyclic carbonates from olefins and CO2

We studied the potential application of an efficient, reusable, and easily recoverable catalyst of dendritic fibrous nanosilica (DFNS)-supported platinum(ii) complexes (DFNS/Pt(ii) NPs) to form cyclic carbonates in the presence of epoxides by converting carbon dioxide. Cyclic carbonates from epoxides and carbon dioxide is proposed as the most appropriate way to synthesis this C1 building block. We performed FE-SEM, TEM, TGA, BET, VSM, and ICP-MS to thoroughly characterize DFNS/Pt(ii) NPs.

Inter- and intramolecular phosphonium salt cocatalysis in cyclic carbonate synthesis catalysed by a bimetallic aluminium(salen) complex

Quaternary phosphonium salts can be used as cocatalysts for the conversion of epoxides and carbon dioxide into cyclic carbonates catalysed by bimetallic aluminium(salen) complexes at ambient temperature and one atmosphere pressure. The phosphonium groups

Ionic Liquid Supported on DFNS Nanoparticles Catalyst in Synthesis of Cyclic Carbonates by Oxidative Carboxylation

In this paper, in the proximity of epoxides, we have suggested the conversion of carbon dioxide (CO2) for cyclic carbonates known as the most proper approach for synthesizing this C1 building block. Oxidation carboxylation of styrenes with CO2 is performed at aerobic conditions utilizing the present approach. Oxidize carboxylation of styrenes by CO2 was performed in the presence of DFNS-IL as NPs. Good to superb performance products were provided deploying DFNS-IL nanocatalyst. In addition, the anatomy of DFNS-IL has been distinguished by various methods, including XRD, VSM, FT-IR, SEM, EDX, TEM, and TGA. The stability of the catalytic system increased after the excessive addition of DFNS. In addition, the hot filtration test provided complete insight into the heterogeneity of the catalyst. The reuse and recycling of the catalyst were repeatedly investigated for coupling reactions. In addition, the mechanism of the coupling reactions was thoroughly studied.

Palladium-salen-bridged ionic networks immobilized on magnetic dendritic silica fibers for the synthesis of cyclic carbonates by oxidative carboxylation

Compared to epoxides, converting carbon dioxide (CO2) to cyclic carbonates is proposed as the most appropriate way to synthesize C1 building blocks. In this study, a Pd(ii) Schiff base complex is fixed on FeNi3/DFNS nanoparticles and then reacted with melamine to provide a recoverable magnetic heterogeneous nanocomposite of FeNi3/DFNS/salen/Pd(ii). It was determined that the FeNi3/DFNS nanoparticles are an appropriate catalyst for the oxidation carboxylation of styrenes with CO2 in a one-step reaction. The FeNi3/DFNS nanoparticles were characterized via XPS, FTIR, EDX, FE-SEM, XRD, TGA, TEM, IC, VSM and BET analyses. The important benefits of this catalyst are its easy work-up, low cost and high efficiency.

Spatially Ordered Arrangement of Multifunctional Sites at Molecule Level in a Single Catalyst for Tandem Synthesis of Cyclic Carbonates

With fossil energy resources increasingly drying up and gradually causing serious environmental impacts, pursuing a tandem and green synthetic route for a complex and high-value-Added compound by using low-cost raw materials has attracted considerable attention. In this regard, the selective and efficient conversion of light olefins with CO2 into high-value-Added organic cyclic carbonates (OCCs) is of great significance owing to their high atom economy and absence of the isolation of intermediates. To fulfill this expectation, a multifunctional catalytic system with controllable spatial arrangement of varied catalytic sites and stable texture, in particular, within a single catalyst, is generally needed. Here, by using a stepwise electrostatic interaction strategy, imidazolium-based ILs and Au nanoparticles (NPs) were stepwise immobilized into a sulfonic group grafted MOF to construct a multifunctional single catalyst with a highly ordered arrangement of catalytic sites. The Au NPs and imidazolium cation are separately responsible for the selective epoxidation and cycloaddition reaction. The mesoporous cage within the MOF enriches the substrate molecules and provides a confined catalytic room for the tandem catalysis. More importantly, the highly ordered arrangement of the varied active sites and strong electrostatic attraction interaction result in the intimate contact and effective mass transfer between the catalytic sites, which allow for the highly efficient (>74% yield) and stable (repeatedly usage for at least 8 times) catalytic transformation. The stepwise electrostatic interaction strategy herein provides an absolutely new approach in fabricating the controllable multifunctional catalysts, especially for tandem catalysis.

Synthesis of Ionic Liquids as Novel Nanocatalysts for Fixation of Carbon Dioxide with Epoxides by Using a Carbon Dioxide Balloon

Abstract: In the present study, the nanocatalyst of imidazolium based ionic liquids (ILs) is synthesized for the fixation of carbon dioxide (CO2) under moderate conditions by utilizing a balloon of CO2 with commercially available epoxides. IL incorporated porous dendritic fibrous nanosilica (DFNS) catalyst (IL/DFNS) was designed and synthesized. The synthesized catalyst was characterized using N2 absorption desorption isotherm, XPS, SEM, EDX, TGA, HR-TEM, and AFM. For cyclic carbonate, an environmental friendly catalyst of porous IL/DFNS indicate highly impressive catalytic efficiency from CO2 through CO2 fixation and epoxides under mild condition. Attendance of polar hydroxyl and anion exchange nature groups of IL frame work to high surface area is known as the main aspect to be reliable for elevated catalytic efficiency and also advance in stability of catalyst and providing a proper recyclability.
