4-ACETAMIDO-TEMPO Chemical Properties,Usage,Production

Chemical Properties

ORANGE-RED CRYSTALLINE POWDER

Uses

4-Acetamido-TEMPO, free radical 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.
