The cover picture shows an efficient and cost‐effective method for the preparation of fluorinated conjugated enynes. 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. More details are discussed in the article by Shen et al . on page 901–907.
