An efficient and cost‐effective method for the preparation of fluorinated conjugated enynes was described. The method was compatible with a variety of functional groups such as chloride, amine, cyano and ester group. The method could also be extended to the coupling of (R,Z)‐3‐(2‐chloro‐1,2‐difluorovinyl)‐4‐alkyloxazolidin‐2‐one (3) with moderate yields.
描述了一种制备氟化共轭烯的有效且经济的方法。该方法与多种官能团兼容,例如氯,胺,氰基和酯基。该方法还可以扩展到中等收率的(R,Z)-3-(2-氯-2-1,2-二氟乙烯基)-4-烷基恶唑烷酮-2-一(3)的偶联。
