Catalytic cross‐coupling is a valuable tool for forming new carbon‐carbon and carbon‐heteroatom bonds, allowingaccess to a variety of structurally diverse compounds. However, for this methodology to reach its full potential, precise control over all competing cross‐coupling sites in poly‐functionalised building blocks is required. Carbon‐fluorine bonds are one of the most stable bonds in organic chemistry

two-step procedure for the site-specific preparation of fluorinated naphthalene and phenanthrenederivatives is described. The Sonogashira reaction of bromofluoro-substituted alkenes with terminal alkynes, followed by base-catalyzed cyclization in refluxing N-methyl-2-pyrrolidinone (NMP), affords the corresponding fluorinated naphthalene and phenanthrenederivatives in good yields.
