Abstract The design of molecular scaffolds bearing multiple functional groups for the activation and ring‐opening epoxides is a crucial challenge synthesis efficient homogeneous heterogeneous catalysts that are used cycloaddition reaction CO 2 to epoxides. Traditional approaches prepare such multifunctional often imply multistep synthetic procedures expensive building blocks. In this work we show bifunctional Lewis acid metal quaternary ammonium halide group can be prepared in just two steps starting from an opportunely designed epoxide precursor by using inexpensive substrates. Such readily accessible catalyst was applied series under atmospheric conditions generally leading quantitative substrate conversion high carbonate selectivities. Importantly, also epoxide‐driven concept developed preparation catalyst, could recyclable systems target reaction.

Polyhydroxyurethanes from Biobased Monomers and CO₂: A Bridge between Sustainable Chemistry and CO₂ Utilization^†

Chinese Journal of Chemistry, Год журнала: 2023, Номер 42(6), С. 652 - 685

Опубликована: Ноя. 7, 2023

Comprehensive Summary Polyhydroxyurethanes (PHUs) have received considerable attention in the last decade as potential alternatives to traditional phosgene‐based polyurethanes (PUs). The development of suitable 5CC (five membered‐ring cyclic carbonate) precursors bearing multiple carbonate moieties (multi‐5CCs) is a key requisite for preparing PHUs by polyaddition reaction with bis‐ or polyamines. Producing sustainable from CO 2 ‐based five‐membered carbonates (5CCs) obtained biobased epoxides valuable strategy bridge utilization and upcycling renewable substrates. In this context, while many multi‐5CC monomers reported literature are oil‐based, recent efforts led large variety multifunctional 5CCs that produced combination resources such fatty acids vegetable oils, lignin, terpenes, sugars. work, crucial advances (2019—2023) on prepared multi‐5CCs (partially/potentially) substrates reviewed respect their synthesis, thermal mechanical properties, recent, emerging applications.

The cycloaddition of CO2 to epoxides afford versatile and useful cyclic carbonate compounds is a highly investigated method for the nonreductive upcycling CO2. One main focuses current research in this area discovery readily available, sustainable, inexpensive catalysts, catalytic methodologies that allow their seamless solvent-free recycling. Water, often regarded as an undesirable pollutant process, progressively emerging helpful reaction component. On one hand, it serves hydrogen bond donor (HBD) enhance performance ionic compounds; on other aqueous media development diverse protocols can boost or ease recycling molecular catalysts. An overview advances use biphasic systems provided work along with recommendations possible future developments.
