The antihypoxic and anticonvulsant activity of eight new amidophosphoryl derivatives of crown ethers was investigated. It was found that some of them exhibit pronounced antihypoxic activity. The results of an x-ray structural and IR spectroscopic stu

The values of the enthalpy and free energy factors (Ej and Cj) of the pnospiiorylic compounds were estimated on the basis of literature (1) and experimental material (2). The ability of carbonylic compounds to H-bond formation was found to be remarka

1. On the basis of a study of vibrational spectra, it has been shown that in dibenzomethylphosphonyl-14-crown-5 and dibenzomethylthiophosphonyl-14-crown-5, the total number of effective electron-donor centers is smaller than in dibenzo-18-crown-6. 2.

1. TheνP=O absorption band of dimethyl (chloromethyl)-, dimethyl(methoxymethyl)- and dimethyl(phenoxymethyl)phosphine oxides is quite sensitive to complexation with a number of metal salts. 2. Complexation constants for these phosphine oxides with c

It has been shown that for dibenzoadamantylphosphonyl-17-crown-6 in the crystalline state and in solutions, the characteristic conformation has separate orientations of the unshared electron pairs of the oxygen atom, owing to the presence of the bulk

1. The existence of conformational equilibrium in which the conformer with the higher dipole moment predominates was demonstrated with the IR and Raman spectra of liquid and crystalline veratrole and the IR spectra of gaseous veratrole. 2. The vibrat
