Tandem dehydrogenation-olefin-metathesis catalyst systems, comprising a pincer-ligated iridium-based alkane dehydrogenation catalyst and a molybdenum-based olefin-metathesis catalyst, are reported to effect the metathesis-cyclooligomerization of cyclooctane and cyclodecane to give cycloalkanes with various carbon numbers, predominantly multiples of the substrate carbon number, and polymers.
据报道,串联式脱氢-烯烃-复分解催化剂体系包含一个夹钳式连接的铱基烷烃脱氢催化剂和一个钼基的烯烃-复分解催化剂,可实现环辛烷和环癸烷的复分解-环低聚,得到具有不同碳原子数的环烷烃,主要是底物碳数和聚合物的倍数。
