✦ Synopsis

Abstract

Allylic alcohols, rather than halides, acetates, or carbonates can be used directly in the Friedel–Crafts‐type coupling with various phenols. The use of a Ru^IV^, rather than a Ru^II^, precursor promotes the formation of one H^+^ per cycle so that a large excess of acid is never present in the reaction mixture. Consequently, the leaving group in the oxidative addition reaction is H~2~O, thereby avoiding the production of an unnecessary by‐product.
