A metal‐free approach to meta‐substituted phenols from cyclohex‐2‐enone via catalytic oxidative aromatization has been developed. The transformations are initiated with a catalytic amount of molecular iodine as the direct oxidant, while dimethyl sulfoxide is employed as the terminal oxidant. This practical approach is capable of avoiding the use of metal promoters and costly reagents, the lengthy synthesis
