“…Many MOFs possess attractive properties for application as heterogeneous catalysts for the cycloaddition of CO 2 to epoxides such as large and accessible pore volume enabling high CO 2 uptake and Lewis acid sites that can activate the epoxide towards reaction with CO 2 . Indeed, various MOFs with available CUS with Lewis acid properties were reported as active catalysts for this type of CO 2 ‐fixation reactions . On the other hand, MOFs typically show structural instability upon attempts to reuse them in consecutive runs.…”

Metal-organic frameworks (MOFs) with accessible Lewis acid sites are finding increasing application in the field of heterogeneous catalysis. However, the structural instability of MOFs when they are exposed to high temperature and/or high pressure often limits their applicability. In this study, two strategies were applied to achieve a MOF catalyst with high stability, activity and selectivity in the reaction of CO with styrene oxide to produce styrene carbonate. In the first approach, a MOF with linkers with high connectivity as MIL-100(Cr) was studied, leading to promising activity and recyclability in consecutive catalytic runs without loss of activity. In the second strategy, a MOF with linkers with lower connectivity but with encapsulated Keggin phosphotungstic acid (MIL-101(Cr)[PTA]) was prepared. However, the activity of this catalyst decreased upon reuse as a consequence of deterioration of the MOF. Further investigations were dedicated to the enhancement of the catalytic performance of MIL-100 and included the variation of the metal centre as well as the type and loading of organic salt acting as nucleophile source. This allowed tuning the nature of the organic halide to the specific porous structure of MIL-100(Cr) to prevent diffusion limitations. The best catalytic performance was obtained for MIL-100(Cr) in combination with EMIMBr ionic liquid, which gave very high styrene carbonate yield (94 %) with complete selectivity after 18 h of reaction at mild temperature (60 °C).

“…We next sought to evaluate the impact of MOF synthesis method and activation procedure on the performance of MIL-101(Cr). 29,30,34 MIL-101(Cr) has several reported preparations in the literature that vary primarily based on the acid utilized. 27,[35][36][37] The role of the acid during synthesis is not completely understood, but it is known that halides derived from the acid as well as hydroxides derived from water are incorporated into the framework during synthesis.…”

“…Indeed, most OMSs are not able to activate dioxygen under mild reaction conditions. 75 , 78 , 79 Very recently, however, Llabrés i Xamena and co-workers showed that MIL-100(Fe) treated under the appropriate conditions before reaction generates a redox pair, Fe 3+ /Fe 2+ , that assists with the generation of peroxides directly from oxygen. 5 , 80 For more information about MOFs used in oxidation reactions, we refer the reader to the recent review by Dhakshinamoorthy et al and to the extensive characterisation on the MIL-100 and MIL-101 families performed by Daturi and co-workers.…”
