Synthesis of nucleoside-substituted carbonate and diol derivatives through the carbon dioxide reaction using polyionic liquid catalysts

Abstract

It is of great significance to high efficiently synthesize compounds with pharmacological activities through CO2 conversion. Herein, a kind of polyionic liquids (PILs) with adjustable structure and multiple active sites...

Ordered mesoporous carbon encapsulated linear poly(ionic liquid)s enabling synergy effect of surface groups and ionic moieties for CO2 fixation under mild conditions

“…A family of carbon encapsulated linear PIL samples, termed X%PIL-T@FDU-15-600 (X% index the loading amount), were prepared by using PIL-T with different loading amounts, including 15%PIL-T@FDU-15-600, 10%PIL-90-FDU-15-600, and 20%PIL-90@FDU-15-600. There was no N element in FDU-15-600 and the detectable N species on X%PIL-T@FDU-15-600 samples reflected the immobilization of PIL-T (Table S1, entries [6][7][8][9][10][11][12]. The PIL content linearly increased with the loading amount, while close to each other by fixing the loading amount.…”

“…In this regard, chemically fixing CO 2 into high-value-added chemicals has attracted great attention in the mitigation of CO 2 emission [7][8][9][10][11]. One of the most promising approaches is the cycloaddition reaction between CO 2 and three-member ring organic compounds such as aziridines and epoxides [12][13][14]. This pathway has the features of environmentally friendly and 100% atom-efficiency [5,8,15], producing a series of valuable chemicals like cyclic carbonates as solvents, polymer monomers, and organic intermediates [16][17][18][19][20].…”

“…This pathway has the features of environmentally friendly and 100% atom-efficiency [5,8,15], producing a series of valuable chemicals like cyclic carbonates as solvents, polymer monomers, and organic intermediates [16][17][18][19][20]. To convert CO 2 molecules with inherent thermodynamic stability and kinetic inertness under mild condition [12,[21][22][23] encouraged the development of various homogeneous and heterogeneous catalysts including metal-porphyrin [6,24], metal complexes [25,26], metal-organic frameworks (MOFs) [27][28][29], covalent organic frameworks (COFs) [30,31], ionic liquids (ILs) [32,33], and porous organic polymers (POPs) [34][35][36], etc. The homogeneous catalysts normally exhibited high activity while the heterogeneous one allows facile catalyst separation and recycling.…”

Photothermal Synergistic Catalysis over Defective Zn3In2S6 for CO2 Fixation

“…Consequently, the capture and utilization of CO 2 has received unprecedented attention in recent years. , Among them, CO 2 cycloaddition reaction holds great promise because of its 100% atomic utilization efficiency and subsequent highly valued cyclic carbonate products. − However, nowadays, industrial routes mainly rely on the traditional TBAB, KI, and other halogen anion nucleophilic reagent homogeneous catalysts, which suffer from low conversion, harsh reaction conditions, and expensive equipment investment . Part of novel catalytic technology based on ionic liquid-based multifunctional homogeneous catalysts is still confronted with high reaction pressure, unsatisfied catalytic efficiency, and homogeneous separation problem. − As a result, developing highly efficient heterogeneous catalysts that can work under mild conditions holds great promise for technological upgrading of CO 2 cycloaddition.…”

Maximizing the ionic liquid content and specific surface area in hierarchically nanoporous hypercrosslinked poly(ionic liquid)s towards the efficient conversion of CO2 into cyclic carbonates

“…8–10 At present, numerous homogeneous and heterogeneous catalysts have been applied to CO 2 cycloaddition. 11–19 Nevertheless, the challenge still remains for this catalytic process that lies in the design of high-efficiency catalysts to promote CO 2 conversion under mild reaction conditions, particularly low temperature and atmospheric pressure.…”
