approach for the activation of triplebonds in ionic liquids (ILs) with anions that can chemically capture CO2 (e.g., azolate, phenolate, and acetate), which can achieve hydration of triplebonds to carbonyl chemicals. It is discovered that the anion-complexed CO2 could abstract one proton from proton resources (e.g., IL cation) and transfer it to the CN or CC bondsvia a six-membered ring transition
在此,我们报告了一种 CO 2介导的碱催化方法,用于激活离子液体 (IL) 中的三键,其中的阴离子可以化学捕获 CO 2(例如,唑盐、酚盐和乙酸盐),从而实现三键的水合羰基化学品。发现阴离子络合的CO 2可以从质子资源(例如IL阳离子)中提取一个质子,并通过六元环过渡态将其转移到C N 或C C 键,从而实现它们的水合。特别是,四丁基鏻 2-羟基吡啶在 CO 2下对腈和含C C 键的化合物的水合显示出高效率气氛,以优异的收率提供一系列羰基化合物。这种催化方案简单、绿色、高效,开辟了一种在温和和无金属条件下通过三键水合获得羰基化合物的新方法。
