Lithium is the key to activate the nucleofuge ability of fluoride in the title transformation (see scheme). This simple and straightforward approach not only provides a practical synthetic method for the preparation of monofluoroalkenes, an important fluorinated motif, but also demonstrates the ability of fluoride to act as a competent leaving group in nucleophilic substitution reactions.
