could effectively catalyze the cycloaddition of CO2 and aziridines in the absence of additional co-catalyst, and it could maintain the catalytic activity after five cycles. Furthermore, 1 also exhibited high catalytic activity for the gram-scale experiment. Importantly, it is the first MOF material as a heterogeneous catalyst for the conversion of CO2 and aziridines without co-catalyst.
CO 2与氮丙啶的环加成反应是获得高价值产品的重要反应。多孔 MOF 可以催化该反应,但仍需要助催化剂来提高催化性能。这种由基于 MOF 的材料在没有助催化剂的情况下催化的反应迄今尚未见报道。在此,合成了一种多孔且稳定的三维(3D)骨架[Ni (DCTP)]·6.5DMF} n ( 1 ),其朗缪尔表面积为3,789 m 2 /g,显示出高I 2吸附能力高达 731.0 mg/g 并且可以可逆地释放。此外,它表现出104.0 cm 3的高 CO 2吸附容量/g at 273 K。研究结果表明,1可以在没有额外助催化剂的情况下有效地催化 CO 2和氮丙啶的环加成反应,并且可以在五个循环后保持催化活性。此外,1还表现出对克级实验的高催化活性。重要的是,它是第一种 MOF 材料,作为非共催化剂转化 CO 2和氮丙啶的非均相催化剂。
