Multiply fluorine-substituted iodo anisoles are efficiently coupled in an Ullmann-type reaction to provide the corresponding bisanisoles. The coupling is selective and even tolerates bromo moieties. Subsequent deprotection of hydroxy groups gives access to highly fluorinated biphenols.

Fluorinatedphenols and other electron-deficient phenolic substrates are efficiently and cleanly iodinated by an iodine/ iodide mixture employing alkaline conditions. This protocol turned out to be the most practical for the generation of such highly fluorinated iodophenols. For later application in coupling processes the protection of the phenolic hydroxy moiety is often required. Therefore, a practical
