The oxidation of alcohols to obtain ketones, aldehydes or carboxylic acids is a fundamental transformation in organic synthesis and many reagents are known for these conversions. However, there is still a demand for mild and selective reagents for the oxidation of alcohols in the presence of other functional groups. As an alternative, the nitroxyl radical TEMPO (2,2,6,6-tetramethylpiperidine-N-oxyl) has been demonstrated to be a useful reagent for the transformation of alcohols. The oxidation of alcohols using TEMPO is often efficient, fast, selective, made in mild conditions and can tolerate sensitive functional groups. In this article we report different methodologies using TEMPO in the oxidation of alcohols.
