摘      要：The highly water-soluble phosphine ligands Na2O3PCH2CH2NH(CH2CH2O)nCH2CH2N- (CH2PPh2)2 (n=1,2,3) were prepared by a new and simple route under mild conditions in good yield; the palladium (II) complexes of the ligands 3a~c with 2:1 or 4:1 -PPh2 to Pd2+ molar ratio were also prepared and characterized .
