✦ Synopsis

Do intramolecular LiF interactions affect the reactivity of aryne precursors? This was the key question for structural studies of lithiated and nonlithiated tetrafluorobenzene. No correlation between LiF distances and the ease of LiF elimination exists, and the lengths of the C~aryl~F bonds in the lithiated compound are less affected by LiF interactions than by the “anionic” character of the benzene ring.
