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%. In addition, the kinetics of the reaction was investigated at different reaction temperatures by calculating the reaction rate constant and activation energy (based on the Arrhenius equation).

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.

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.

Polycarbonates with pendant functional groups have attracted much attention due to their capability for further chem. modification and post-polymerization This work describes the synthesis of a poly(carbonate-co-ether) with massive pendant acrylate groups from the copolymerization of glycidyl methacrylate (GMA) with carbon dioxide (CO₂), using a nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co(III) DMCC) catalyst. The carbonate linkage content (F_CO2) of the poly(carbonate-co-ether) could be varied from 42.2 to 68.0% by changing the polymerization conditions.
