新型氧螯合茚基钌催化剂在烯烃复分解反应中的研究展望

Olefin metathesis is a transition metal-mediated transformation that rearranges the carbon atoms of the carbon-carbon double bond of olefins, which is a key reaction in organic, polymer chemistry. The development of new well-defined, highly active and selective catalysts is a very desirable and valuable goal. This review mainly overviewes various modifications on new oxygen-chelated indenylidene ruthenium catalysts, explained the difference in the catalytic activity on ring-closing metathesis reaction (RCM) and selectivity on cross metathesis reaction (CM). Finally, the perspectives on the development of this type of catalysts are summarized.
