Disclosed herein are methods for synthesizing fatty olefin metathesis products of high Z-isomeric purity from olefin feedstocks of low Z-isomeric purity. The methods include contacting a contacting an olefin metathesis reaction partner, such as acylated alkenol or an alkenal acetal, with an internal olefin in the presence of a Z-selective metathesis catalyst to form the fatty olefin metathesis product. In various embodiments, the fatty olefin metathesis products are insect pheromones. Pheromone compositions and methods of using them are also described.
本文揭示了一种从低Z异构纯度的烯烃原料合成高Z异构纯度脂肪烯烃转化产物的方法。该方法包括在存在Z选择性转化催化剂的情况下,将烯烃转化反应伙伴(如酰化烯醇或烯醛
缩醛)与内部烯烃接触,形成脂肪烯烃转化产物。在各种实施方式中,脂肪烯烃转化产物是昆虫信息素。还描述了信息素组合物及其使用方法。
