complexe containing macrocyclic N-heterocyclic carbene ligand with two small aryl arms tied together was obtained and characterised. Interestingly, it can exist in two forms, cis and trans. Both of them exhibit similarly high thermodynamic stability, yet different application profiles in catalysis, however both can be used in difficult metathesis reactions, also leading to the formation of tetrasubstituted
获得并表征了新的 Grubbs 型配合物,该配合物含有大环 N-杂环卡宾配体和两个小芳基臂连接在一起。有趣的是,它可以以两种形式存在,顺式和反式。它们都表现出相似的高热力学稳定性,但在催化中的应用曲线不同,但是两者都可以用于困难的复分解反应,也会导致四取代双键的形成。
