摘要：

The novel water-soluble ligand, N,N-bis(diphenylphosphinomethyl)-2-amino-ethylphosphonic acid, (Ph2PCH2)(2)NCH2CH2PO3H2, had been synthesized. in quantitative yield by reaction of 2-aminoethylphosphonic acid with bis(hydroxymethyl)-diphenylphosphonium chloride in water. Its mono- and disodium salts, which can be used as water-soluble ligands for transition metal complex catalysts, were also easily prepared under mild. conditions.
