Do intramolecular LiF interactions affect the reactivity of aryne precursors? This was the key question for structural studies of lithiated and nonlithiated tetrafluorobenzene. No correlation between LiF 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 LiF interactions than by the “anionic” character of the benzene ring.
