<p>The invention concerns a method for preparing beta-phosphorous nitroxide radicals which consists in preparing in a first step an aminophosphonate by reacting a carbonyl compound, a primary amine and a phosphorous compound, then in a second step in oxidising said aminophosphonate using non-halogenated organic peracids in a two-phase organic water/solvent medium with a buffered aqueous phase with a pH ranging between 5 and 12.</p> |
