Transition metal complexes of ditertiary aminomethylphosphine ligand, (Ph2PCH2)NCH3 [N, N-bis (diphenylphospinomethyl)aminomethane], dppam, with metal ions which are Ag(I), Au(I), Cu(I), and Co(II) have been synthesized under nitrogen atmosphere by the Schlenk method. [Ag(dppam)2]NO3 (1), [Au(dppam) 2]Cl (2), and [Cu(dppam)2]Cl (3) complexes have been isolated as colorless solids, whereas [CoCl2 (dppam)J (4) complex as a blue solid. All complexes have been characterized by atomic absorption, FT-IR, NMR (1H, 13C, 31P) spectroscopic, thermogravimetric/differantial thermal analysis (TG/DTA), and elemental analysis techniques. Antimicrobial activity of 1, 2, 3, and 4 were studied in vitro on 13 bacteria and 4 yeasts. The cobalt(II) phosphine complex has shown the best antimicrobial activity in comparison with the other metal complexes.

α-Aminoacids, their esters and sodium salts may be transformed by a modified Mannich-reaction into N-phosphinomethyl or N,N-bis(phosphinomethyl) derivatives.The sodium or triethylammonium salts of the chiral bisphosphines L-(-)-N,N-bis(diphenylphosphinomethyl)-alanine and -valine may be used as ligands to form enantioslective hydrogenation catalysts with rhodium complexes.The highest optical yield achieved was 29percent.
