Catalytic, Kinetic, and Mechanistic Insights into the Fixation of CO₂ with Epoxides Catalyzed by Phenol-Functionalized Phosphonium Salts was written by Hu, Yuya;Wei, Zhihong;Frey, Anna;Kubis, Christoph;Ren, Chang-Yue;Spannenberg, Anke;Jiao, Haijun;Werner, Thomas. And the article was included in ChemSusChem in 2021.SDS of cas: 13818-44-5 This article mentions the following:

A series of hydroxy-functionalized phosphonium salts were studied as bifunctional catalysts for the conversion of CO₂ with epoxides under mild and solvent-free conditions. The reaction in the presence of a phenol-based phosphonium iodide proceeded via a first order reaction kinetic with respect to the substrate. Notably, in contrast to the aliphatic analog, the phenol-based catalyst showed no product inhibition. The temperature dependence of the reaction rate was investigated, and the activation energy for the model reaction was determined from an Arrhenius-plot (E_a=39.6 kJ mol^-1). The substrate scope was also evaluated. Under the optimized reaction conditions, 20 terminal epoxides were converted at room temperature to the corresponding cyclic carbonates, which were isolated in yields up to 99%. The reaction is easily scalable and was performed on a scale up to 50 g substrate. Moreover, this method was applied in the synthesis of the antitussive agent dropropizine starting from epichlorohydrin and phenylpiperazine. Furthermore, DFT calculations were performed to rationalize the mechanism and the high efficiency of the phenol-based phosphonium iodide catalyst. The calculation confirmed the activation of the epoxide via hydrogen bonding for the iodide salt, which facilitates the ring-opening step. Notably, the effective Gibbs energy barrier regarding this step is 97 kJ mol^-1 for the bromide and 72 kJ mol^-1 for the iodide salt, which explains the difference in activity. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5SDS of cas: 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.SDS of cas: 13818-44-5

Catalytic conversion of carbon dioxide using phase transfer catalysts was written by Park, D. W.;Moon, J. Y.;Yang, J. G.;Lee, J. K.. And the article was included in Energy Conversion and Management in 1997.Application In Synthesis of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate This article mentions the following:

Syntheses of 5-membered cyclic carbonates from CO₂ and glycidyl methacrylate or diglycidyl 1,2-cyclohexanedicarboxylate were investigated in view of the characteristics of phase-transfer catalysts, reaction mechanisms, and kinetics. Quaternary salts showed good conversion of epoxide at 1 atm of CO₂ pressure. Among the salts tested, those having a larger alkyl group and a more nucleophilic counter-anion exhibited better catalytic activity. Kinetic studies in a semi-batch reactor, through which a slow stream of CO₂ was continuously passed, showed that the reaction rate was pseudo-first order with respect to epoxide. In a batch autoclave reactor with high CO₂ pressure, however, the reaction rate showed second order kinetics. The reaction was also carried out with an insoluble phase-transfer catalyst, quaternary ammonium chloride anchored to metal oxide, to facilitate the recovery of catalyst. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Application In Synthesis of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate).

Nanoparticles of aromatic biopolymers catalyze CO₂ cycloaddition to epoxides under atmospheric conditions was written by Jaroonwatana, Wimalin;Theerathanagorn, Tharinee;Theerasilp, Man;Del Gobbo, Silvano;Yiamsawas, Doungporn;D’Elia, Valerio;Crespy, Daniel. And the article was included in Sustainable Energy & Fuels in 2021.Recommanded Product: (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate This article mentions the following:

Lignin and melanin are aromatic biopolymers that are contained in large amounts in plants and animals. Biopolymers containing hydrogen bond donor (HBD) moieties such as phenols, or some amino acids, are sustainable catalytic components for the synthesis of useful cyclic carbonates by cycloaddition reaction of CO₂ to epoxides. However, their application is typically restricted to the use of bulk materials requiring harsh reaction conditions for efficient conversion. In the search for more efficient and sustainable bio-based heterogeneous HBDs, we extract and produce microparticles of melanin from various sources as well as kraft lignin nanoparticles and apply them for the cycloaddition of carbon dioxide to epoxides. Importantly, nanoparticles from lignin and melanin can efficiently catalyze the reaction under atm. conditions at moderate temperatures (60°C) using low loadings of external nucleophiles. Moreover, lignin nanoparticles are functionalized with catechol groups, leading to more efficient catalysts for the conversion of a series of epoxides to the corresponding cyclic carbonates. The phenolated lignin nanoparticles, acting as heterogeneous hydrogen bond donors, can be recovered and used at least 10 times with similar performance. Addnl., the origin of the catalytic activity of the biopolymers is investigated in relation to their morphol. and composition Nanoparticles of aromatic biopolymers are promising and inexpensive renewable platforms for efficient CO₂ fixation to produce useful chems. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Recommanded Product: (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate).

Succinimide-KI: An efficient binary catalyst system for mild, solvent-free cycloaddition of CO₂ to epoxides was written by Li, Qingshuo;Chang, Haibo;Li, Runming;Wang, Hongxia;Liu, Jichun;Liu, Shanhu;Qiao, Congzhen;Lin, Tong. And the article was included in Molecular Catalysis in 2019.SDS of cas: 13818-44-5 This article mentions the following:

The succinimide (SI)-KI is an efficient catalyst system to synthesize propylene carbonate (PC) from carbon dioxide (CO₂) and propylene oxide (PO) at a solvent-free condition. A synergistic effect was observed between SI and KI that largely increased the reaction yield. It enabled the cycloaddition reaction to take place at 70 °C under a low pressure (0.4 MPa) for only 4 h, with a PC yield as high as 97.5%. The overall condition is milder than the reaction catalyzed by most of the other KI involved co-catalyst systems reported in literatures. The excellent catalytic ability was explained by the increased KI solubility in PO due to the presence of SI and the weak acidity of NH in SI which can be enhanced by KI. A reaction mechanism was proposed based on a reaction kinetics study. SI-KI was applicable to cycloaddition of CO₂ with other epoxides such as 2-methyl-acrylic acid oxiranylmethyl ester, 2-phenyl-oxirane, 7-oxabicyclo[4.1.0]heptane, etc. It may offer an inexpensive, environmentally-friendly route to the synthesis of propylene carbonate from CO₂.

Phosphorus-based Bifunctional Organocatalysts for the Addition of Carbon Dioxide and Epoxides was written by Werner, Thomas;Buettner, Hendrik. And the article was included in ChemSusChem in 2014.Formula: C8H10O5 This article mentions the following:

Bifunctional phosphonium salts were synthesized and employed as organocatalysts for the atom efficient synthesis of cyclic carbonates from CO₂ and epoxides for the first time. These catalysts were obtained in high yields by a modular, straightforward one-step synthesis. The hydrogen-bond donating alc. function in the side chain leads to a synergistic effect accelerating the catalytic reaction. The desired cyclic carbonates are obtained in high yields and selectivity under solvent-free reaction conditions without the use of any co-catalyst. Under optimized reaction conditions various epoxides were converted to the corresponding cyclic carbonates in excellent yields. The products were obtained anal. pure after simple filtration over a silica gel pad. This protocol is even applicable for a multigram reaction scale. Moreover, the catalysts could be easily recovered and reused up to five times.

Design of hybrid nonisocyanate polyurethane coatings for advanced ambient temperature curing applications was written by Asemani, Hamidreza;Zareanshahraki, Forough;Mannari, Vijay. And the article was included in Journal of Applied Polymer Science in 2019.Related Products of 13818-44-5 This article mentions the following:

This study is focused on development of environmentally benign, two component, high solid, nonisocyanate Polyurethane (NIPU) coatings through a novel route based on cyclic carbonate/amine chem. Cyclic carbonates are synthesized and reacted with an excess amount of amine to yield polyurethane polyamines (PUPAs). Coatings are then prepared by using stoichiometric proportions of PUPAs and aliphatic epoxies as crosslinkers and their coating properties are studied. Results reveal that by proper design of NIPU oligomers-functional group content, backbone structure, and mol. weight (M_n)-coatings with outstanding performance features such as low temperature flexibility and resistance to chems. can be obtained and selected coatings containing PUPA with M_n = 1480 and 1:1.5 mol ratio of low-mol.-weight amine exceed the performance of a conventional isocyanate-based reference sample. Elimination of isocyanates, substantially reduced volatile organic compounds as well as fast ambient curing, make these polyurethane coatings a promising alternative for various industrial applications. © 2018 Wiley Periodicals, Inc.J.

Facile CO₂ Cycloaddition to Epoxides by Using a Tetracarbonyl Metal Selenotungstate Derivate [{Mn(CO)₃}₄(Se₂W₁₁O₄₃)]^8- was written by Lu, Jingkun;Ma, Xinyi;Singh, Vikram;Zhang, Yujiao;Wang, Ping;Feng, Junwei;Ma, Pengtao;Niu, Jingyang;Wang, Jingping. And the article was included in Inorganic Chemistry in 2018.Quality Control of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate This article mentions the following:

A novel polyoxometalate cluster, i.e., Na_1.5H_4.5[(CH₃)₄N]₂{[Mn(CO)₃]₄(Se₂W₁₁O₄₃)}·9H₂O (1), has been successfully synthesized under moderately acidic conditions. Compound 1 contains four electron-donating {Mn(CO)₃}⁺ organometallic entities, which are grafted over an unprecedented heteropolytungstate electron-acceptor group. Compound 1 was further structurally characterized by various physicochem. techniques like elemental analyses, inductively coupled plasma (ICP) analyses, IR and UV-vis spectroscopy, electrochem., and single-crystal X-ray diffraction, and so on. The polyoxoanion of 1 comprises a novel {Se₂W₁₁} fragment, which is obtained from mol. assembly of rare {SeW₃} and {SeW₈} species. Evaluation of the data from solution-state IR spectrum showed excellent agreement with the solid state IR spectrum, indicating the intact clusters in the CH₃CN/Na₂SO₄ solvent. Also, neg. electrospray ionization mass spectrometry (ESI-MS) was an alternative tool to verify the stability of 1 in the mixed solvent. Addnl., the resulting hybrid can act as a catalyst for cyclic carbonate formation from the reactants epoxides and CO₂ under modest reaction conditions in conjunction with a 1-ethyl-1-methylpyrrolidinium bromide (2). The good activity can be substantiated due to the cooperative influence of polyoxoanion and Br^– ions. Complex 1 can also be easily recycled and reused three times without obvious decrease of catalytic activity.

Free radical polymerization study of glycerin carbonate methacrylate for the synthesis of cyclic carbonate functionalized polymers was written by Camara, Fatoumata;Caillol, Sylvain;Boutevin, Bernard. And the article was included in European Polymer Journal in 2014.Electric Literature of C8H10O5 This article mentions the following:

This article describes for the first time a complete study of the free radical polymerization (FRP) of (2-oxo-1,3-dioxolan-4-yl) Me methacrylate or glycerin carbonate methacrylate (GCMA). This methacrylic cyclic carbonate compound allows the synthesis of polymers bearing cyclic carbonate functional groups which can be used for crosslinking reactions in other to form urethane linkages without the use of harmful isocyanates. Transfer reactions to the cyclic carbonate moiety were identified during the polymerization of GCMA. Moreover, a transfer constant of 0.011 was obtained when a cyclic carbonate compound, the acetate of glycerin carbonate is used as transfer agent during the polymerization of MMA. A calculation of the k²_p/k_t value of GCMA in DMSO proves the high reactivity of this monomer since the value obtained (245 × 10^-3 L mol^-1 s^-1) is almost 2 times higher than Me methacrylate (MMA) value (149 × 10^-3 L mol^-1 s^-1) in the same conditions. Glass transition temperatures of homopolymers of GCMA (114 and 134 °C) were measured for the first time. Finally the calculation of the reactivity ratios rMMA (0.5) and rGCMA (2.0) during the copolymerization of GCMA with MMA in DMSO, by the Macret’s method shows again the high reactivity of this monomer.
