1956年,Eleuterio引用了现在被称为烯烃复分解反应的方法来解释某些非均相Mo催化剂如何从丙烯生产聚乙烯;他提出丙烯转化为2-丁烯和乙烯,然后乙烯选择性聚合。[1] 20世纪70年代,人们对催化烯烃复分解反应产生了浓厚的兴趣,这是因为人们能够使用钨、钼和钯催化剂(使用各种配方制备)从环烯烃合成各种聚合物,并且人们意识到烯烃复分解在有机化学中的潜在应用。烯烃复分解反应的公认机理,其基本版本如公式1所示,由Hérrison和Chauvin在1971年提出(公式2),2
In 1956 Eleuterio invoked what is now known as an olefin metathesis reaction in order to explain how certain heterogeneous Mo catalysts could produce polyethylene from propylene; he proposed that propylene was converted into 2-butene and ethylene and that ethylene was then selectively polymerized. 1 An intense interest in the catalytic olefin metathesis reaction developed in the 1970s as a consequence of the ability to synthesize various polymers from cyclic olefins using tungsten, molybdenum, and rhenium catalysts (prepared using a variety of recipes) and as people became aware of potential applications of olefin metathesis in organic chemistry. The accepted mechanism of the olefin metathesis reaction, the basic version of which is shown in eq 1, was proposed in 1971 by Hérrison and Chauvin (eq 2), 2
