Hydroxylation of C-alkylated phenols has benn achieved by employing cerium(IV) ammonium nitrate and hydrogen peroxyde in acetic acid medium.The yield of hydroxylation products increases markedly when 3*E-3 M solution of sodium dodecyl sulphate is added to the oxidation system.The plausible mechanism of the reaction seems to involve free radical intermediates and is influenced by hydrophobic environment.The finding are also of significance from the view point of oxidative coupling of phenols.
