The capture and conversion of carbon dioxide (CO₂) into useful and valuable chemicals are receiving more and more research interesting. Herein, we designed a new and efficient route to synthesize methyl phenyl carbonate (MPC) via the carbonylation of phenol (PhOH) with CO₂ and methanol (CH₃OH). PhOH and CH₃OH react with 1,8-diazabicyclo-[5.4.0]undec-7-ene (DBU) to form ionic liquids [DBUH][PhO] and [DBUH][CH₃O]. The DBU-based ionic liquids exhibited outstanding performance in CO₂ capture and in situ conversion at room temperature. The reusability of the system had no obviously change after 6 cycles. This protocol provides a sustainable and environmentally friendly preferential technique for the production of MPC, and extends the chemical utilization of CO₂.

二氧化碳 (CO ₂ )的捕获和转化为有用和有价值的化学品正受到越来越多的研究。在此，我们设计了一种新的高效路线，通过苯酚 (PhOH) 与 CO ₂和甲醇 (CH ₃ OH)的羰基化合成碳酸甲基苯酯 (MPC )。PhOH 和 CH ₃ OH 与 1,8-二氮杂双环-[5.4.0] undec-7-ene (DBU) 反应形成离子液体 [DBUH][PhO] 和 [DBUH][CH ₃ O]。基于 DBU 的离子液体在 CO _{2 中}表现出优异的性能在室温下捕获和原位转化。6个循环后系统的可重用性无明显变化。该协议为 MPC 的生产提供了一种可持续和环保的优惠技术，并扩展了 CO ₂的化学利用。
