Solubilities of tertiary phosphines and their complexes in water

9 SOLUBILITIES OF TERTIARY PHOSPHINES AND THEIR COMPLEXES IN WATER 

Almost no data can be found in the literature on the solubility of metal complexes with water-soluble phosphine ligands. It is mentioned that 5 kg( ) of the highly charged Pd-complexes, [PdX2 P(CH2CH2NMe2H)3 2]6+ (X = Cl, Br) dissolved in 1 kg water at 25 °C [64], 

At the end of this Chapter, looking at the exceptional variety of water-soluble ligands and the pace with which newer and newer compounds are synthetized it is safe to state that every aqueous reaction may find its perfect catalyst - at least the ligands are out there already. It seems that high-throughput screening could benefit aqueous organometallic catalysis, too.
