    • Olefin Methathesis is accomplished by combining olefins with acetylenes andungsten salts such as tungsten hexachloride. This process simplifies olefin metathesis as acetylenes can be handled in the atmosphere, while ethylaluminum dichloride or related materials which have been used in the past instantaneously ignite when exposed to the atmosphere. Furthermore, the acetylenes bring about the reaction with much greater speed than when the initiator is a combination of a metal carbene and an acetylene. Besides, double bonds introduced in the polymer are highly stereoselective.
    • 烯烃元素通过将烯烃与乙炔和钨盐如六氯化钨组合来完成。 该方法简化了烯烃复分解,因为乙炔可以在大气中处理,而当暴露于大气中时,过去使用的二氯化乙基铝或相关材料瞬间点燃。 而且,与引发剂是金属卡宾和乙炔的组合相比,乙炔产生的反应速度要快得多。 此外,在聚合物中引入的双键是高立体选择性的。
