Halogenation of phenols and phenyl ethers with potassium halides in the presence of 18-crown-6 on oxidation with m-chloroperbenzoic acid
Abstract
Several types of phenyl ethers have been monobrominated in the ring in good yields with potassium bromide in the presence of 18-crown-6 on oxidation with m-chloroperbenzoic acid. Monoiodination takes place with both phenyl ethers and free phenols when potassium iodide is employed.
