Oxidative Demethylation

Various alkyl-substituted p-dimethoxybenzenes (ArH) react readily with nitric acid and sulfuric to form nitro-products (ArNO2). When the nitric acid is used in excess, the nitro-product react via either nitration to dinitro-compound (Ar(NO2)2) or via oxidative demethylation to nitro- p-quinone (Q). As such, the competition between the nitration, polynitration and oxidative dealkylation is effectively modulated by the added nitric acid and the alkyl-substituted p-dimethoxybenzenes.
