Publisher SummaryThe oxidation of phenols has many different aspects. Oxidative coupling, the formation of cyclohexadienones, and conversion to quinones and other carbonylic and transformation products (other than those obtained by electrophilic substitution or rearrangement of phenyl esters) are considered. This chapter discusses the chemistry of alkylphenols. A comparison of phenolic coupling on solid potassium permanganate and on potassium manganate surfaces has been made to emulate the natural biological process. Cyclohexadienones can be considered structurally as hemiquinones, and they have been synthesized by a variety of simple approaches in which invariably a substituent becomes attached to the 2- or 4- position and the structure becomes locked.
