Fluorine makes the difference! Bis(2,2′-biphenoxy)borates decorated with fluorine substituents have been synthesized and studied in supercapacitor test cells (see scheme). A clear trend towards higher electrochemical stability with the increase of the fluorine content has been observed. For a maximum performance, only two fluorine substituents per benzene moiety are required.

Fluorinated phenols 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 iodination and subsequent methylation sequence was elaborated providing the highly fluorinated anisoles with good to excellent yields. The developed method is applicable for a broad scope of fluorinated phenols and analogues.

Figure Presented. 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 gro
