Functionalized IRMOF-3 as efficient heterogeneous catalyst for the synthesis of cyclic carbonates

Functionalized isoreticular metal–organic framework-3 (IRMOF-3) was developed as a novel heterogeneous catalyst for the solventless synthesis of cyclic carbonates without any co-catalyst. The results showed that functionalized IRMOF-3 performed excellent activity, selectivity and reusability. The effects of reaction temperature, pressure, and time on the yield of propylene carbonate were tested. And the reaction mechanism was also discussed.

Graphical abstractFunctionalized IRMOF-3 was developed as a novel heterogeneous catalyst for the solventless synthesis of cyclic carbonates without any co-catalyst. It performs excellent catalytic activity and selectivity. After simple separation, it can be reused without viewable loss of activity. And the framework can be retained after the coupling reaction.Figure optionsDownload full-size imageDownload high-quality image (136 K)Download as PowerPoint slideHighlights► Functionalized IRMOF-3 was developed as a novel heterogeneous catalyst for the synthesis of cyclic carbonates. ► F-IRMOF-3 performed excellent activity and reusability without any co-catalyst. ► The framework of functionalized IRMOF-3 contains acid (Zn2+) and basic (I−) bi-active centers. ► There are synergetic catalytic effect between acid and basic centers.
