[en] Full text: The derivatives of acids of phosphorus, due to variety of properties, are a subject of numerous researches. Now it is known, that the derivatives of acids of phosphorus apart from insect, neurotoxic, antienzym and other kinds of physiological activity have also complex forming properties. As extra gents of noble metals particularly are analyzed by the derivatives of dithio phosphor of acids although organ phosphorus compounds with one nuclear of sulfur make extraction properties. Therefore, with the purpose of detection of effective extra gents of ions of argentum the phosphorylated derivatives of heterogeneous ring compounds were synthesized: Ph(RO)P(O)Cl + HOCH(CH₃)CH₂-R^'-> Ph(RO)P(O)OCH(CH₃)CH₂-R^' + HCl. R C₂H₅ - C₆H₁₃, R^' = a piperidine, morpholine, anabasine Structure of the obtained connections is confirmed by the results IR -, Pm- and mass- spectrometry. In an IR-spectrum O-hexyl-O - [piperidynoisopropyl] phenylphosphonate has lines of absorption bands of the following functional groups (ν, cm^-1): (P-O-C₅H₁₁) 990-1000, (P = 0) 1260, (P-C₆H₅)1450, (C-N in cycle) 1550. In an IR-spectrum O-pentyl-[anabasinoisopropyl] phenylphosphonate has lines of absorption bands of the following functional groups (ν, cm^-1): (P-O-C₅H₁₁) 990-1000, (P = 0) 1250, (P-C₆H₅)1450, (C-N in cycle) 1550. In a spectrum PMR about O-pentyl-[morpholyniisopropyl] phenylphosphonate in the field of a weak field (7, 18-7, 29 p.m.) the multiplet about tones of phenyl group is watched. Me tin proton resonate at 4,66 m.d.as multiplet The signals O-CH₂ of protons of morpholinic cycle appear at 3,58 m.d.. 4H) by the way of triplet. The protons N-CH₂ (6H) three methylene groups will derivate a composite multiple at 2, 10-2, 70 m.d.. The signal of metil group's protons (3H) is watched at 1,15m.d.as doublet. Final metal group resonates at 0, 87 p.m. Six of C-CH₂ of groups give a complex signal in the field of 1, 2-1, 8 m.d. The obtained connections are analyzed as extra gents of ions of argentum from salt-sulphate acid medium. Process of extraction was analyzed by a method of radioactive nuclides of metals (¹¹⁰Ag). The synthesized connections have appeared by weak extra gents of ions of argentum irrespective of the nature and density of inorganic acids. As the results of the lengthening of alkyl radicals in a molecule there is a rise of efficiency of extraction of metals. By rather more effective extra gent of metal has appeared in phosphorylated derivative of anabasine (E = 52 %)
