Converting CO2 into valuable chemicals is an effective way to alleviate the high level of global CO2. The cycloaddition reaction and propylene oxide (PO) has atomic economy advantage environmental friendliness compared with traditional phosgene method carbonate (PC). Due chemical inertness CO2, catalysts are needed make proceed smoothly. Through rational design, a multifunctional catalyst that combines activation sites attack PO adsorption can be formed. At same time, use harmful substances reduced by making catalytic process more environmentally friendly. In this work, we discuss research progress synthesis PC from PO. Starting mechanism, system summarized perspective design. homogeneous catalysts, focus on effect composition performance. heterogeneous heterogenization (preparation methods), including supported, confined, polymerized catalysts. addition, promising photocatalysis biomass catalysis especially introduced. Finally, in order experimental results move toward industrial production, several problems existing industrialization discussed, production equipment, influence source, product/catalyst separation.

Five- and six-membered heterocycles containing nitrogen or oxygen have been considered as privileged scaffolds in organic chemistry the chemical industry because of their usage high-value commodities. Herein, we report a two-dimensional (2D) Cu(II)-based MOF catalyst, IITKGP-40, via strategic employment ample Lewis acid–base bifunctional sites (open metal nodes free pyrazine moieties) along pore wall. IITKGP-40 could convert toxic CO2 to cyclic carbonates an atom-economical manner under solvent-free conditions aromatic aldehyde bioactive 1,4-DHPs Hantzsch condensation. Exceptional catalytic performance (99%) turnover number mild reaction for fixation using sterically hindered styrene oxide, good-to-excellent yields wide range aldehydes toward 1,4-dihydropyridines (1,4-DHPs) make promising multipurpose heterogeneous catalyst. Moreover, demonstrate practical utility two biologically important drug molecules, diludine nitrendipine analogue, also synthesized. is recyclable at least three consecutive runs without significant loss activity, making it real-time applications.

Strategic utilization of carbon dioxide as both a mitigation tool and sustainable C1 feedstock represents pivotal pathway toward green chemistry. Although poly(ionic liquid)s (PILs) exhibit promise in CO2 conversion, conventional divinylbenzene (DVB) cross-linked architectures are limited by reduced ionic density accessibility active sites. Herein, we reported binuclear imidazolium-functionalized PIL catalyst (P-BVIMCl), synthesized through simple self-polymerization process, derived from rationally designed liquid monomers formed quaternization 1,4-bis(chloromethyl)benzene with N-vinylimidazole. The dual sites P-BVIMCl-quaternary ammonium cation (N+) nucleophilic chloride anion (Cl−) synergistically enhanced adsorption/activation epoxide ring-opening. Under optimal preparation conditions (100 °C, 24 h, water/ethanol = 1:3 (v/v), 10 wt% AIBN initiator) reaction 2.0 MPa CO2, mmol epichlorohydrin, 6.7 loading, 3.0 h), P-BVIMCl catalyzed the synthesis glycerol carbonate (GLC) yield up to 93.4% selectivity 99.6%, maintaining activity close 90% after five cycles. Systematic characterization functional theory (DFT) calculations confirmed synergistic activation mechanism. This work established paradigm for constructing high-ionic-density catalysts molecular engineering, advancing development high-performance PILs industrial valorization.

One use of CO2 as a starting material in organic transformations is the synthesis cyclic carbonates and polycarbonates. Due to low reactivity CO2, this transformation must be carried out presence an efficient catalyst. Although several catalytic systems have been developed last decade, reducing pressure at which reaction remains one main challenges process. In context, present work, we describe activity mixed metal oxides (MMOs) from (1 atm) epoxides 70 °C. The these materials catalysts represents great advantage since they are highly stable economical can reused cycles.
