Abstract: The novel water-soluble ligand, N,N-bis(diphenylphosphinomethyl)-2-aminoethylphosphonic acid, (Ph₂PCH₂)₂NCH₂CH₂PO₃H₂, 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.

Keywords: N; N-Bis(diphenylphosphinomethyl)-2-aminoethylphosphonic acid; Synthesis
