order to design improved ruthenium catalysts for Z-selective olefin metathesis reactions, four cyclometalated catalysts with new chelated architectures were synthesized, structurally characterized, and tested in metathesis assays. The mechanism of formation of each was explored using DFT calculations. Of note, two complexes are derived from activation of a tertiary C–H bond, and one features a four-membered
为了设计用于Z-选择性烯烃复分解反应的改进的钌催化剂,合成了四种具有新螯合结构的环金属化催化剂,对其结构进行了表征,并在复分解测定中进行了测试。使用DFT计算探索了每种化合物的形成机理。值得注意的是,两种配合物是从叔碳键的活化作用衍生而来的,一种具有四元螯合结构。此外,还分离并研究了两个未进一步进行C–H活化的二戊二酸酯配合物,并进行了研究以阐明有关影响环金属化的因素的信息。
