Achieving efficient dissolution of carbon monoxide (CO) in the solvent is very helpful for the implementation of carbonylation reaction at ambient pressure. However, almost all of common solvents show very low solubilities of CO at high temperature. Herein, a series of cuprous‐based ternary deep eutectic solvent (DES) was prepared by mixing imidazolium hydrochloride with CuCl and ZnCl2. The ternary DES [BimH]Cl‐CuCl‐1.0ZnCl2 exhibited very large CO absorption capacity (0.075 mol mol−1, 1 bar) even at a high temperature (353.2 K), which is superior to all of the reported absorbents. Moreover, the ternary DES [BimH]Cl‐CuCl‐1.0ZnCl2 could further promote the reactive absorption of CO to conduct the aminocarbonylation reaction effortlessly at ambient pressure, and thus the targeted products benzamides were obtained in 70–97 yields. We believe that this finding opens a new way to design advanced solvents for efficient capture of CO at high temperature.

含铜的三元深共熔溶剂在高温下促进了CO的吸收

实现一氧化碳(CO)在溶剂中的有效溶解对于在环境压力下进行羰基化反应非常有帮助。但是,几乎所有常见的溶剂在高温下都显示出非常低的CO溶解度。本文通过将咪唑盐酸盐与CuCl和ZnCl 2混合制备了一系列基于亚铜的三元深共熔溶剂(DES)。即使在高温(353.2 K)下,三元DES [BimH] Cl-CuCl-1.0ZnCl 2仍表现出非常大的CO吸收能力(0.075 mol mol -1,1 bar),优于所有报道的吸收剂。此外,三元DES [BimH] Cl‐CuCl‐1.0ZnCl 2可以进一步促进CO的反应性吸收,从而在环境压力下毫不费力地进行氨基羰基化反应,因此目标产物苯甲酰胺的收率为70-97。我们相信,这一发现为设计高级溶剂以在高温下有效捕集CO开辟了一条新途径。
