Among the water-soluble phosphines sulfonated arylphosphines have been widely studied, particularly in the field of organometallic chemistry and biphasic catalysis because such ligands accord water-solubility to coordination compounds and thus afford means to separate easily the organic components from the catalysts in the aqucous phase 1–3. More recently, mono- and tri-sulfonated triphenylphosphine have found applications in organic synthesis for the preparation of specifically deuterated alkenes and more generally for nucleophilic additions in water4–8. Sulfonated triarylphosphines or alkyldiarylphosphines have been prepared by sulfonation with oleum of the corresponding phosphines on one or several aromatic nuclei9–11. The sulfonation leads usually to mixtures of compounds having various degrees of sulfonation and to oxidation at phosphorus which forces subsequent separations11–12. On the other hand this direct sulfonation method is not convenient for the synthesis of hydrophilic phosphines be... |
