摘要: By using 31P NMR and IR techniques it is established that the basicities of triphenylphosphine m-trisulfonate (TPPTS) (PPh3) are in same order magnitude. This highly hydrosoluble phosphine a convenient ligand for synthesis coordination compounds molybdenum(0), palladium(II), platinum(II) rhodium(I). The exchange TPPTS with ligands other than PPh3 (nitriles, carbon monoxide, olefins, chloride) can be used to obtain desired complexes. However, because redox reactions between metal salts, water possible, lowvalent precursors must carried out experimental conditions have carefully controlled avoid side-reactions participation sulfonate anions competitive reactions.
