Application

1)TEMPO is employed in organic synthesis as a catalyst for the oxidation of primary alcohols to aldehydes. The actual oxidant is the N-oxoammonium salt. In a catalytic cycle with sodium hypochlorite as the stoichiometric oxidant, hypochlorous acid generates the N-oxoammonium salt from TEMPO.

2)TEMPO itself is relatively inexpensive, but there are TEMPO derivatives that are often used such as 4-hydroxy-TEMPO (TEMPOL) or 4-acetamido-TEMPO that have cheaper precursors. Examples of TEMPO use in chemical industry are bisnoralcohol (a steroid) to bisnoraldehyde conversion by Upjohn and retinol to retinal conversion by Novartis. One industrial method employs H5PV2Mo10O40 as co-oxidant, the reduced form of which can be reoxidized by atmospheric oxygen. Polymer-supported TEMPO catalysts are also commercially available.
