Brik, H. Remita, M. Delcourt] Using radiolysis of chloroform /CHCl3/, 3,5-dibromo-4-oxo-2,2,6,6-tetramethyl-piperidin-1-oxyl /1/ is oxidized to its corresponding oxoammonium bromide /3/. The mechanism is a one electron oxidation forming the oxoammonium ion /3/ which is stabilized by a bromide counter ion. Br− is generated through a one-electron reduction of /1/ resulting in a Br− loss and the formation of a second product. The reaction is quantitative. Compound /3/ which is non paramagnetic is easily studied by NMR and gives access to the structure of /1/. Radiolysis then reveals to be a highly selective oxidation process.
