Although the olefin metathesisreaction is a well‐known and powerful strategy to get alkenes, this reaction remained highly challenging with fluororalkenes, especially the Cross‐Metathesis (CM) process. Our thought was to find an easy accessible, convenient, reactive and post‐functionalizable source of fluoroalkene, that we found as the methyl 2‐fluoroacrylate. We reported herein the efficient ruthenium‐catalyzed

New chemical reactions of 1,1,2-trifluoro-1,3-butadiene provide simple access to a series of new fluorinated alkene derivatives. These derivatives provide a simple, general methodology for the stereocontrolled preparation of 2-fluoro-2-alkenoate esters and related monofluoroalkene derivatives which include fluoro analogs of known insecticides, pheromones or pharmaceuticals. A new method for the preparation of 1,1,2-trifluoro-1,3-butadiene is also provided.
