And the article was included in Molecular Catalysis in 2018.Application of 13818-44-5 This article mentions the following:

In this study, synthesis of cyclic carbonates from epoxide and CO₂ using polyvinyl alc. (PVA) and potassium iodide (KI) as an efficient catalytic system is reported. The catalytic reaction happens in solvent-free conditions. A synergetic effect occur between PVA and KI which considerably increases the reaction yield. This binary catalytic system is mainly suitable for mono-substituted terminal epoxides. In the optimized reaction condition, over 90% reaction yield can be achieved. The binary catalyst is reusable and can be recycled at least five times without significant loss of the catalytic activity. The PVA hydrolysis degree affect the catalytic activity as well. A possible mechanism of synergetic effect of the binary system was proposed. PVA and KI may form a non-toxic, low cost, recyclable, highly-efficiency catalyst for fixing CO₂ through cycloaddition with epoxides. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Application of 13818-44-5).

(2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Application of 13818-44-5

Fixation of carbon dioxide concurrently or in tandem with free radical polymerization for highly transparent polyacrylates with specific UV absorption was written by Liu, Bin;Zhang, Ying-Ying;Zhang, Xing-Hong;Du, Bin-Yang;Fan, Zhi-Qiang. And the article was included in Polymer Chemistry in 2016.Category: dioxole This article mentions the following:

It is still a challenging issue to combine the coupling reaction and free radical polymerization (FRP) for well-controlled and efficient synthesis of polyacrylates bearing the cyclic carbonate group from carbon dioxide (CO₂) and vinyl epoxides. This work describes the efficient catalytic synthesis of poly(2-oxo-1,3-dioxolane-4-yl)methyl methacrylate (PDOMA) from CO₂ and glycidyl methacrylate (GMA) via concurrent or tandem combination of the coupling reaction and FRP. In a concurrent reaction, GMA/CO₂ coupling with 100% oxirane conversion was achieved by using a nanolamellar zinc-cobalt (3) double metal cyanide complex [Zn-Co³⁺ DMCC] (0.30 mol% Zn related to GMA) with cetyltrimethylammonium bromide (0.65 mol% related to GMA) as the catalyst, and PDOMA was obtained via the concurrent free radical polymerization of carbon-carbon double bonds in the presence or absence of addnl. free radical initiator. In the tandem process, (2-oxo-1,3-dioxolane-4-yl)methyl methacrylate (DOMA) was firstly synthesized via GMA/CO₂ coupling catalyzed by Zn-Co(3) DMCC/CTAB and purified by simply passing through a basic aluminum oxide column. DOMA could be polymerized via solution or emulsion polymerization, leading to linear PDOMA or PDOMA nanoparticles with minimized metal residues. The obtained PDOMAs were soluble in strong polar solvents and presented excellent light transmittance in a wavelength range of 314-800 nm (93%) and perfect UV absorption in a wavelength range of 200-313 nm (close to 100%), while most of the common polyacrylates cannot absorb UV light. In addition, the PDOMAs had tunable number-average mol. weights (M_ns) of 12.0-132.0 kg mol^-1 and high glass transition temperatures (T_gs) of 121.0-140.4 °C. Such CO₂-based PDOMAs could be potentially used as wavelength-specific UV-absorbing materials. This work provides a simple and useful synthetic path to directly utilize CO₂ by combining two reaction mechanisms.

Herein, a copper-alumina spinel hollow sphere with a triple-shell structure developed and applied as a novel catalyst for the cycloaddition of CO₂ at atm. pressure. Different operating conditions such as reaction temperature, various solvents and reaction time were studied in this reaction. Besides, different epoxides were converted into corresponding substituted dioxolanones I [R = CH₂Cl, Ph, CH₂OC₆H₅, etc.] at 80°C, under bubbling of CO₂ at atm. pressure, a catalyst loading of 3 weight% and a reaction time of 24 h with isolated yields up to 100%.

Prudent Choice of Iron-based Metal-Organic Networks for Solvent-free CO₂ Fixation at Ambient Pressure was written by Mitra, Antarip;Biswas, Tanmoy;Ghosh, Sourav;Tudu, Gouri;Paliwal, Khushboo S.;Ganatra, Pragati;Mahalingam, Venkataramanan. And the article was included in European Journal of Inorganic Chemistry in 2022.Safety of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate This article mentions the following:

The rising global warming and associated climate change demand efficient tactics to reduce CO₂ concentration in the atm. Conversion of epoxides to cyclic carbonates using CO₂ is a promising and sustainable approach towards CO₂ fixation. However, the inert nature of CO₂ and high activation energy requirement for the particular reaction necessitate the use of efficient catalysts. The authors have designed and developed a heterogeneous catalyst using catechol functionalized guanidinium based ligands (L1) and Fe(III) ions to perform the CO₂ fixation reaction. The resulting amorphous material (Fe-L1) possesses metal-organic network as revealed through different characterization methods. The optimized catalyst Fe-L1 is efficient for the conversion of a variety of epoxides into their corresponding cyclic carbonates in very good yield (>80%). The reactions were performed under atm. pressure without solvent and external additives (e. g., TBAI or KI). The investigation of the mechanistic pathway indeed validates the synergistic effect of metal and halide ions that leads to the efficient conversion of different epoxides into cyclic carbonates. Also, no significant loss in the catalytic activity of the Fe-L1 is noticed up to six cycles. The post catalytic analyses clearly indicate the robust nature of the catalyst. The developed one component bifunctional catalytic system can pave way towards transition to sustainable carbon capture and conversion.
