| 摘要 |
<p>An environmentally friendly process is described for the preparation of 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl or of a 4-acylamino-2,2,6,6-tetramethylpiperidine-N-oxyl by the carbonate-mediated hydrogen peroxide oxidation of 4-hydroxy-2,2,6,6-tetramethylpiperidine or of a 4-acylamino-2,2,6,6-tetramethylpiperidine. The reaction can also be run in the absence of any catalyst.</p> |
