With a view to understanding the role of the catalyst in olefin metathesis various attempts were made to synthesize possible intermediates of the reaction. No compound was formed which could account satisfactorily for a metathesis reaction under conditions favourable for the formation of tungstacyclopentane. Attempted synthesis of tungstacyclobutane also failed, but gave results which could be interpreted
为了理解催化剂在烯烃复分解中的作用,进行了各种尝试来合成反应的可能的中间体。在有利于钨环戊烷形成的条件下,没有形成可以令人满意地说明易位反应的化合物。钨丝环丁烷的尝试合成也失败了,但是给出的结果可以解释为模仿复分解。尽管达成了这种明显的协议,但得出的结论是,如果实际上形成钨环丁烷,它们会分解为钨卡宾(烷基亚乙基钨)和烯烃,而不是钨环戊烷,然后分解为烯烃。
