reports the ring-closing metathesis reaction of bisolefins, including a reluctant fluoroalkenes, linked with oxaza moiety. The resulting heterocycles were produced in high yields under high diluting conditions disfavoring the homodimerization side reaction of nonfluorinated double bond. The use of a mixture of solvents proved to be a good strategy to obtain the fluorinated heterocycles in fair to excellent
摘要 本研究报告了双烯烃的闭环复分解反应,包括与 oxaza 部分连接的不情愿的氟代烯烃。在不利于非氟化双键的均二聚化副反应的高稀释条件下以高产率生产所得杂环。事实证明,使用溶剂混合物是一种很好的策略,可以以一般到极好的收率获得氟化杂环。
