By using 31 P NMR and IR techniques it is established that the basicities of triphenylphosphine m ‐trisulfonate (TPPTS) and triphenylphosphine (PPh 3 ) are in the same order of magnitude. This highly hydrosoluble phosphine is a convenient ligand for the synthesis of hydrosoluble coordination compounds of molybdenum(0), palladium(II), platinum(II) and rhodium(I). The exchange of TPPTS with ligands other than PPh 3 (nitriles, carbon monoxide, olefins, chloride) can be used to obtain the desired complexes. However, because redox reactions between metal salts, water and TPPTS are possible, the synthesis of lowvalent precursors must be carried out and the experimental conditions have to be carefully controlled to avoid side‐reactions and the participation of the sulfonate anions in competitive reactions.
