A method for the synthesis of hypotensive alkyl(phenyl)[omega-(N-phenylpiperazino)alkyl]-phosphine oxides by reacting alkyl(omega-haloalkyl)phenylphosphine oxides with N-phenylpiperazine was elaborated. Phenyl[gamma-(N-phenylpiperazino)propyl]propylphosphine oxide reacts with alkyl halides to give [gamma-(N-alkyl-N'-phenylpiperazinio)propyl]phenyl(propyl)oxophosphine halides.
