TEMPO (2,2,6,6-Tetramethylpiperidinyloxy or 2,2,6,6-Tetramethylpiperidine 1-oxyl) and its derivatives are stable nitroxy radicals used as catalysts in organic oxidation reactions. TEMPO was discovered by Lebedev and Kazarnovskii in 1960. The stable free radical nature of TEMPO is due to the presence of bulky substituent groups, which hinder the reaction of the free radical with other molecules.
