摘要 |
The present invention relates to a process for the preparation of beta-phosphorated nitroxide radicals which consist in preparing, in a first step, an aminophosphonate by reaction of a carbonyl compound, of a primary amine and of a phosphorous compound in the presence of a Lewis acid and then, in a second step, in oxidizing the said crude aminophosphonate using nonhalogenated organic peracids in a water/organic solvent two-phase medium with an aqueous phase buffered at a pH ranging from 5 to 12. |
