Abstract 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 ...
