描述了使用Cp* RuCl（cod）催化剂进行α，ω-联烯炔的环二聚反应。该反应通过炔与丙二烯的内部双键的氧化环加成生成的亚烷基双烯并环戊烯中间体进行，以高产率得到具有两个五元环和三个四元环的独特的五环化合物。
The cyclodimerization of alpha,omega-allenynes using Cp* RuCl(cod) catalyst is described. This reaction proceeds via an alkylidene ruthenacyclopentene intermediate, which is generated by the oxidative cycloaddition of alkyne and the internal double bond of the allene, to give a unique pentacyclic compound having two five-membered rings and three four-membered rings in high yields.
