“…The activities of ILs could be greatly improved by adding metal salts or complexes for the synthesis of cyclic carbonates. Furthermore, synergistic effects on promoting the cycloaddition reactions of epoxides have been reported [31,[34][35][36][37][38][39][40][42][43][44][45][46][47][48][49][50][51][52].…”

This review presents the synergistic effect in the catalytic system of ionic liquids (ILs) for the synthesis of cyclic carbonate from carbon dioxide and epoxide. The emphasis of this review is on three aspects: the catalytic system of metal-based ionic liquids, the catalytic system of hydrogen bond-promoted ionic liquids and supported ionic liquids. Metal and ionic liquids show a synergistic effect on the cycloaddition reactions of epoxides. The cations and anions of ionic liquids show a synergistic effect on the cycloaddition reactions. The functional groups in cations or supports combined with the anions have a synergistic effect on the cycloaddition reactions. Synergistic catalytic effects of ILs play an important role of promoting the cycloaddition reactions of epoxides. The design of catalytic system of ionic liquids will be possible if the synergistic effect on a molecular level is understood.

“…[42] To overcome the problems of catalyst separation with these systems, efforts in the application of heterogeneous catalysts have been undertaken. One main strategy concerned the immobilization of homogeneous catalysts onto solid supports, [30,34,43,44] but also metal oxides, like ZnO/ SiO 2 [45] or MgO, [46] catalyzed the reaction. In addition, porous materials like MCM-41, [47] Cs zeolites [48] or aminefunctionalized Ti(Al)-SBA-15 [49] were used.…”

A series of mixed-linker metal-organic frameworks (MIXMOFs) of the general formula Zn 4 O(BDC) x (ABDC) 3-x has been synthesized and tested as catalyst in the reaction of propylene oxide (PO) and carbon dioxide. Based on MOF-5 a new synthetic route was developed which allows the partial substitution of benzene-1,4-dicarboxylate (BDC) linkers in the material by functionalized 2-aminobenzene-1,4-dicarboxylate. In that way the number of catalytically active amino groups can be tuned using the desired BDC/ABDC ratio. The presence of MIXMOFs (instead of a mechanical mixture of MOF-5 and IRMOF-3) was proven by high-resolution X-ray diffraction and DTG. XRD and TG/MS analysis revealed that pure MIXMOF materials can be obtained up to an ABDC loading of 40 %. The thermal stability in air is decreasing with increasing ABDC content from 450°C for pure MOF-5 (0 % ABDC) to ca. 350°C for the 40 % MIXMOF Zn 4 O(BDC) 1.8 (ABDC) 1.2 . Consequently, MIXMOF materials represent a promising class of materials for catalytic applications in the temperature range at least up to 300°C which is

“…The homogeneous catalysts are alkali metal salts [3,4], organotin or organoantimony compounds [5,6], ionic liquids or onium salts [7][8][9][10][11][12][13][14][15][16][17][18][19][20], and transition metal complexes [21][22][23][24][25][26][27][28][29][30][31]. For heterogeneous interactions, metal oxides [32][33][34], zeolites [35,36], smectites [37,38], and polyoxometalate [39,40] are used. Generally, the homogeneous catalysts are superior to the heterogeneous ones in catalytic performance.…”

3-(2-Hydroxyl-Ethyl)-1-Propylimidazolium Bromide Immobilized on SBA-15 as Efficient Catalyst for the Synthesis of Cyclic Carbonates via the Coupling of Carbon Dioxide with Epoxides

3-(2-hydroxyl-ethyl)-1-propylimidazolium bromide (HEPIMBr) was immobilized onto SBA-15, Al-SBA-15 mesoporous molecular sieves and SiO 2 by chemical grafting method. The materials were characterized and used as catalysts for solvent-free synthesis of cyclic carbonates from CO 2 and epoxides under relatively mild conditions. Among them, the HEPIMBr immobilized on SBA-15 performs the best, showing carbonate selectivity and yield of ca. 100% (120°C, 2.0 MPa, 2 h). The catalyst is thermally stable and shows good reusability. Based on the experimental results, a plausible reaction mechanism has been proposed for the catalytic reaction.
