CO₂ Cycloaddition Reactions Catalyzed by an Ionic Liquid Grafted onto a Highly Cross‐Linked Polymer Matrix

One‐Step Synthesis of Thermosensitive Nanogels Based on Highly Cross‐Linked Poly(ionic liquid)s

“…[10] Nevertheless, when the imidazolium-based IL (ImIL), 1-vinyl-3-(ethoxycarbonyl)methyl imidazolium chloride was copolymerized with a cross-linker under the same conditions, the copolymers precipitated from the solvent, resulting in particles in the submicrometer range. [11] Similar results were also reported by Han et al [12] The precipitation of ImIL-based cross-linked copolymers from the solvent during the polymerization process was due to the lower number of poly(ImIL) chains in the copolymer. [11] This result was presumably caused by the lower polymerization reactivity of ImIL monomers, as compared with the cross-linkers.…”

Multilayered Supported Ionic Liquids as Catalysts for Chemical Fixation of Carbon Dioxide: A High‐Throughput Study in Supercritical Conditions

“…This behaviour was previously described for other supported ionic liquid heterogeneous catalysts. [33][34][35][36][38][39] Notably, the best of our catalysts, SBA-15ÀBr(b), shows very high catalytic activity: after 1 h reaction at 80 bar it gives a very good epoxide conversion (75 %) and reaches 90 % after 3 h reaction, in all cases with a complete selectivity towards the cyclic carbonate product (Figure 4). A direct comparison with previously reported catalysts is hindered by the different loadings of ionic liquid on the various catalysts and by the variety of reaction conditions employed in the literature (Table S2 in the Supporting Information).…”

Ionic Liquids: The Synergistic Catalytic Effect in the Synthesis of Cyclic Carbonates

“…As cycloaddition of CO 2 with epoxides are 100% atom-economical reactions, the synthesis of cyclic carbonates has received increasing attention [3,12,13]. It is desirable to find a new type of material for catalyzing the cycloaddition of epoxides and CO 2 although numerous catalysts including both homogeneous and heterogeneous catalysts have already been developed [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Ionic liquids (ILs) have only attracted considerable attention as promising catalysts in the last two decades, although they have been known for almost a century [31].…”
