PHOSPHORUS-31 NMR an‎d FAB-MASS SPECTROSCOPES TO CONFIRM SYNTHESIS OF DIAMINE(DIPHOSPHINE)RUTHENIUM(II) COMPLEXES STARTING FROM DIAMINE(ETHER PHOSPHINE)RUTHENIUM(II) COMPLEXES VIA PHOSPHINE LIGANDS EXCHANGED

The ligands exchange of the ether-phosphine (Ph2PCH2CH2OCH3) on the diamine(etherphosphine)ruthenium(II) with 1,3-bis(diphenylphosphino)propane as a bidentate chelate ligandsuccessfully occurs to produce diamine[1,3-bis(diphenylphosphino)propane]ruthenium(II) complexes in agood yields under vigorous stirring for one week in an inert atmosphere using dichloromethane as solvent.Several ether-phosphine-RuC12 complexes with different types of diamine have been tested to confirm thesubstitution method. In order to collect more information about the system 31P{1H} NMR and 13C{1H}NMR as well as FAB- Mass spectroscopy have been investigated in parallel way to control and supportthe ligands exchange reaction processes.
