The cyclocoupling of epoxides and CO2 was investigated using porphyrin-based Cu(II) metal-organic frameworks with 2D coordination networks. A variety of mono- and disubstituted epoxides were transformed into cyclic carbonates under mild and neat conditions. Several control experiments were carried out to elucidate that the catalytically active site is the dicopper paddle wheel unit rather than the
使用具有二维配位网络的卟啉基 Cu(II) 金属有机骨架研究了环氧化物和 CO2 的环偶联。各种单取代和双取代的环氧化物在温和纯净的条件下转化为环状碳酸酯。进行了几个对照实验以阐明催化活性位点是双铜桨轮单元而不是铜卟啉复合部分。模型桨轮单元的密度泛函理论计算证实了所提出的机制。
