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. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Safety of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate).
(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.Safety of (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate
