Poly(tertiary phosphines and arsines). 15. Some polyphosphines with terminal dialkylamino and alkoxy groups

“…We have also reported several polyphosphines containing terminal hydrogen atoms bonded to the trivalent phosphorus atoms through phosphorus-hydrogen bonds.6 Related poly(tertiary phosphines) containing PCH2CH2P structural units have also been studied by other research groups. [7][8][9] This paper describes the first polyphosphines containing PCH2CH2P structural units and dialkylamino or alkoxy terminal groups bonded to the trivalent phosphorus atoms through phosphorus-nitrogen and phosphorus-oxygen bonds, respectively. The polyphosphines containing terminal methoxy groups provide chelating ligands with stronger x-accepting properties than the previously available polyphosphines,3-5 in which only carbon atoms are bonded to phosphorus.…”
