| 摘要 |
The invention relates to an improved process for preparing alkoxyamines resulting from ß-phosphorated nitroxides corresponding to formula (I), by reaction with a halogen derivative in the presence of an organometallic system. This process comprises carrying out the reaction in a water-miscible organic solvent, and precipitating the alkoxyamine directly from the organic medium by adding an aqueous solution of a strong acid. These alkoxyamines can be used in particular as radical polymerization initiators. |
