چکیده
|
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.
