Full details as well as the study of the scope, limitations, and further elaboration of a straightforward approach to the synthesis of 2,5,7-trisubstituted benzo[b]furans from 2-bromo- and 2-chloro-6-iodo-4- substituted phenols through a consecutive copper- and/or palladium-catalyzed assembly and functionalization process is described. Functionalization at the C(7) position is carried out by Suzuki-Miyaura cross-coupling, alkynylation, alkenylation, and C-N bond forming reactions. A one-pot protocol for the synthesis of 2,5,7-trisubstituted benzo[b]furans is also reported.

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
