Synthesis of cyclic carbonates of different epoxides using CO2 as a C1 building block over Ag/TUD-1 mesoporous silica catalyst: A solvent free approach

A thiol-containing zirconium MOF functionalized with silver nanoparticles for synergistic CO2 cycloaddition reactions

“…53,78,85,86 The catalytically active Zr,Ag centre of the thiol MOF catalyst acts as an active centre and synergistically binds with the electron-rich oxygen atom of the terminal epoxide. 53,78,85,86,88,100,101 Then the bromide ion of the co-catalyst TBAB reacts with the α-carbon of the polarised epoxy ring to open it, which then readily reacts with CO 2 to form an intermediate anion. This intermediate anion is prone to ring closing, which forms cyclic carbonate with the regeneration of the catalyst.…”

“…[80][81][82][83][84][85][86] In particular, for catalytic conversion of terminal epoxides to cyclic carbonates, different silver complexes, 87 silver-based MOFs, 85 and silver nanoparticle incorporated materials have been utilized. 83,84,86,88 In a recent report Li et al demonstrated that silver active sites surrounded by gold nanoclusters show efficiency in the ring-opening of epoxides, and the incorporation of CO 2 can act as a driving force for the conversion. 89 Still detailing the use of silver-containing materials in the cycloaddition of epoxides is primarily an uncharted territory.…”

Silver Nanoparticle-Functionalized Postsynthetically Modified Thiol MOF UiO-66-NH-SH for Efficient CO2 Fixation

“…61−64 Despite the benefits of carbon capture and storage techniques, the chemical inertness of CO 2 makes this process extremely challenging, which is attempted to be circumvented through various catalysts. 64−66 A variety of materials, including zeolites, porous organic polymers (POPs), 67 covalent organic frameworks (COFs), 68,69 metal−organic frameworks (MOFs), 70,71 and nanoparticle-supported materials, 72,73 have been used as catalysts to convert propargylic alcohol and terminal epoxide to corresponding cyclic carbonates. Due to the inertness of CO 2 , the reaction conditions used with these catalysts are relatively harsh.…”

In‐situ Synthesis of Ionic Liquids on B‐doped Mesoporous SiO2 Catalyst for Epoxide‐CO2 Cycloaddition

“…Nevertheless, the high energy-cost process prevented the wide industrialization for CO 2 conversion to cyclic carbonates due to the inert and stable CO 2 molecule. Over the past two decades, abundant homo-or hetero-geneous catalysts have emerged for CO 2 cycloaddition catalysis, such as ionic liquids (ILs), [4,5] organic-metal complexes, [6,7] metal-organic frameworks (MOFs), [8,9] modified mesoporous SiO 2 [10,11] and porous carbon. [12,13] Among these catalysts, ILs can effectively catalyze epoxide-CO 2 cycloaddition owing to its special ion pair structure.…”
