✦ Synopsis

Diaryl ethers are readily synthesized in high yield at room temperature through the copper(II)-prorooted coupling of arylboronic acids and phenols. The reaction is tolerant of a wide range of substituents on both coupling partners. These reaction conditions permit the racemization-free arylation of phenolic amino acids, methodology that has been applied to an efficient synthesis of thyroxine.
