摘要：

为了得到稳定性更好、活性更高的烯烃复分解催化剂,本文采用有机合成的方法,以钌卡宾烯烃复分解催化剂为主体,用锌卟啉进行修饰,得到锌卟啉修饰的Grubbs-Hoveyda型双核钌卡宾烯烃复分解反应催化剂,产物结构使用核磁共振方法进行表征。用0.1%化学计量催化剂催化几种代表性底物闭环复分解(RCM)反应产率能达到95%,对于特定的交叉烯烃复分解反应(CM),延长反应时间也能得到93%的较高产率。研究结果为Grubbs-Hoveyda催化剂的修饰提供了新方法和理论依据。

Abstract:

A zinc-containing porphyrin-modified Grubbs-Hoveyda type binuclear ruthenium carbene olefin metathesis catalyst was synthesized. The structure of the product was confirmed by nuclear magnetic resonance(NMR). The yield of the ring-closing metathesis(RCM) reaction of several representative substrates could reach 95% by using 0.1% steriochemic catalyst. For a specific cross-olefin metathesis reaction(CM), a higher yield(93%) could be obtained with extended reaction time. This study provides a new method and a theoretical basis for the modification of Grubbs-Hoveyda catalyst.
