Abstract
The invention relates to the synthesis of tertiary phosphine oxides and also to certain tertiary phosphine oxides. According to the invention, an organic phase containing a halogenomethyl derivative, an hydroxymethylphosphine oxide and a phase transfer catalyst is reacted, in an organic medium, with an aqueous phase containing an inorganic base. The halogenomethyl derivative can be a micromolecule or a macromolecule. Tertiary phosphine oxides are substances which are useful, in particular, in fireproofing, in hydrometallurgy and in the field of plant protection.
