Sheng Chen, Chunfa Xu, Long Lu and Qilong Shen Palladium-Catalyzed Cross-Coupling of Fluorinated Vinyl Chlorides with Terminal Alkynes: A General Protocol to Fluorinated Enynes Chinese Journal of Chemistry 31
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.
