Basic ion-exchange resins, one kind of polystyryl-supported tertiary amine, were demonstrated to be highly efficient and recyclable catalysts for the fixation of carbon dioxide with aziridines under mild conditions, leading to the formation of 5-aryl-2-oxazolidinone with excellent regio-selectivities. Notably, neither solvents nor any additives were required, and the catalyst could be recovered by
碱性离子交换树脂是一种聚苯乙烯基负载的叔胺,被证明是高效且可循环使用的催化剂,可在温和条件下用氮丙啶固定二氧化碳,从而形成具有优异性能的5-芳基-2-恶唑烷酮区域选择性。值得注意的是,既不需要溶剂也不需要任何添加剂,并且催化剂可以通过简单的过滤来回收,并且可以直接重复使用至少五次,而不会显着降低催化活性和选择性。本协议已应用于环氧化物/炔丙基胺与CO 2 / CS 2的反应。因此,这种无溶剂工艺代表了CO 2的环保催化转化 成为增值化学品,并可能在工业中的各种连续流反应器中具有潜力。
