A Very Simple Copper‐Catalyzed Synthesis of Phenols Employing Hydroxide Salts

Abstract

Cheap and cheerful: The direct copper-catalyzed hydroxylation of activated and unactivated aryl iodides or bromides has been achieved using metal hydroxide salts (MOH). Selective hydroxylation in a H2O/co-solvent system avoids formation of the related biaryl ether by-product and the low cost of the copper catalytic system makes this method very competitive.
