Cyclic organic carbonates from furanics: Opportunities and challenges

Enhancing the Catalytic Performance of Group I, II Metal Halides in the Cycloaddition of CO2 to Epoxides under Atmospheric Conditions by Cooperation with Homogeneous and Heterogeneous Highly Nucleophilic Aminopyridines: Experimental and Theoretical Study

“…Carbonates 6f , and 6g , are attractive building blocks for the synthesis and functionalization of polymers. Both carbonates could be synthesized efficiently and selectively by using 4 /NaI or 4 /MgI 2 in 12 or 24 h, respectively (Table , entries 14–17).…”

“…Although both metal-based and organocatalytic systems can be applied for the catalytic coupling of CO 2 and epoxides, − there is still a significant performance gap between these families of catalysts, with the former being generally more efficient. Therefore, several metal-based homogeneous catalysts have been prepared for the cycloaddition of CO 2 to epoxides where Lewis acidic metal or metalloid centers are harnessed by salen-type, − porphyrin, − triphenolate − ligands, and other scaffolds. − The limitation of such compounds is that their preparation may require several synthetic steps, often by using expensive building blocks/reagents, and generally leads to high-molecular weight metal–organic species that would require highly efficient heterogenization and recyclability in order to be cost-competitive.…”

Polymeric Materials Based on Carbon Dioxide: A Brief Review of Studies Carried Out at the Faculty of Chemistry, Warsaw University of Technology

“…Studies carried out at the CCTP on the physicochemical, mechanical, and biodegradable properties indicate that some of the CO 2 -based polymers can be suitable candidates for practical application as adhesives, biomaterials, smart materials, and components of CO 2 capture systems. Finally, it is worth noting that the recently developed metalbased and organocatalytic systems can be effectively applied to the preparation of a large family of structurally and chemically complexed bio-based cyclic carbonates, which can be easily obtained from epoxidized vegetable oils, sugars, and residual agricultural biomasses [17,52,[85][86][87]. Although synthetic strategies concerning the valorization of CO 2 and biomass to valuable polymeric materials are still in their early stages, they may offer exciting possibilities to create a renewable carbon economy and contribute to the more sustainable use of resources in the coming years.…”

Sustainable valorisation of renewables through dialkyl carbonates and isopropenyl esters

“…Some furanic derivatives are readily transformed in COC-functionalised monomers for NIPU synthesis. 128 For example, Monbaliu and co-workers performed scalable DMC-based carbonylation reactions under sustainable, continuous flow (CF) conditions starting from DMC and FUR- and/or HMF-derived 1,2-diols without additional additives, as depicted in Scheme 15, bottom. CF carbonylation occurred in the presence of an organocatalyst, tetrabutylammonium bromide (TBAB).…”
