【Abstract】 The highly water\|soluble phosphine ligands, H\-2O\-3PCH\-2CH\-2N(CH\-2CH\-2O) n CH\-2CH\-2N(CH\-2PPh\-2)\-2 ( n =1,2,3), and their disodium salts were prepared with good yields by a new route using bis(hydroxymethyl)diphenylphosphonium chloride and N\|substituted 2\|aminoethylphosphonic acid, \{H\-2O\-3PCH\-2CH\-2N\|\}(CH\-2CH\-2O) n CH\-2CH\-2NH\-2 under mild conditions. The compounds 3a~3c were also characterized by IR, NMR and XPS.更多还原
