| 4-ACETAMIDO-TEMPO Usage And Synthesis |
| Chemical Properties | ORANGE-RED CRYSTALLINE POWDER |
| Uses | 4-Acetamido-TEMPO, free radical oxidizes alcohols to carbonyl compounds in the presence of TsOH. |
| Uses | Oxidizes alcohols to carbonyl compounds in the presence of TsOH. |
| General Description | 4-Acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl undergoes one-electron oxidation and reduction reactions. Reaction products were analyzed by 1H, 13C and 15N NMR spectral data. |
| Purification Methods | Dissolve the 1-oxyl in CH2Cl2, wash it with saturated K2CO3, then saturated aqueous NaCl, dry (Na2SO4), filter and evaporate. The red solid is recrystallised from aqueous MeOH, m 147.5o. [Ma & Bobbitt J Org Chem 56 6110 1991, Rozantsev & Kokhanov Bull Acad Sci USSR, Div Chem Sci 15 1422 1966, Beilstein 22/8 V 174.] |
