N,N‐Dimethylaminophenyl moiety is a common fragment in medicinal chemistry as several pharmaceuticals bearing this privileged motif are on the market and under clinical evaluation. Oxidative N‐demethylation is generally regarded as the major metabolic pathway. However, pharmacokinetics, metabolites studies as well as the further structural modification are precluded by the impracticality of chemical

A binuclear copper‐salicylate complex, [Cu(Sal)2(NCMe)]2 (Sal=salicylate), was found to be an active catalyst for the oxidation of N,N‐dimethylanilines by O2, affording the corresponding N‐methyl‐N‐phenylformamides as major products. The reactions were carried out with a O2 balloon and the S/C (substrate/catalyst ratio) of the model reaction could be up to 1×105, providing a practical and highly efficient

selective oxidation of various alcohols (1 mmol). The system yielded good to quantitative conversions (42–100%) of various secondaryalcohols, such as 2-octanol, fenchyl alcohol and borneol, to their corresponding ketones. Primaryalcohols, for example 1-octanol and differently substituted benzylalcohols, were mainly converted to their corresponding carboxylic acids. Studies with a selection of hydrocarbons
