PROCEDE DE PREPARATION DE RADICAUX NITROXYDE B-PHOSPHORES

摘要

The invention concerns a method for preparing beta -phosphorus nitroxide radicals which consists in first preparing an aminophosphonate by reacting a carbonyl compound, a primary amine and a phosphorus compound in the presence of a Lewis acid, then in oxidising said raw aminophosphonate using non-halogenated organic peracids in an organic two-phase water/solvent medium with a buffered aqueous phase with a pH ranging between 5 and 12.
