Structure and reactivity of nitrogen-containing derivatives of carbonyl compounds

Conclusions The oscillopolarographic behavior of certain phenylhydrazones, semi- and thiosemicarbazones in buffered solutions was studied, and the possibility of oscillopolarographic monitoring of the conversions of aliphatic phenylhydrazones was demonstrated.Translated from Ivestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 292–296, February, 1967.     

Structures and reactivities of nitrogen-containing derivatives of carbonyl compounds

A number of products of the condensation of aminotriazole with substituted benzaldehydes were synthesized. Their UV spectra in ethanol and concentrated sulfuric acid are presented. The change in the UV spectra on passing from one solvent to another is explained by the change in the conjugation of the N-N bond. The basicities of the nitrogen atoms were compared by the Pariser-Parr-Pople method.See [1] for communication XXXII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 559–564, April, 1971.     

Investigation of the tautomerism and geometric isomerism of nitrogen-containing derivatives of carbonyl compounds

Summary By means of polarographic and microcoulometric methods it was shown that the reduction of semi- and thiosemicarbazones of acetophenone, p-chloroacetophenone and p-aminoacetophenone and also benzophenone semicarbazone at a dropping mercury electrode takes place irreversibly with participation of two electrons.     

The synthesis and structure of ferrocenylalkyl onium derivatives of nitrogen-containing heterocyclic compounds

The reactions of hydroxymethylferrocene, -hydroxyethylferrocene, and 1,1-bis(-hydroxyethyl)ferrocene withN-ferrocenylalkyl-substituted benzotriazoles, hexamethylenetetramine, and azaferrocene in the CH₂Cl₂ — 48% aqueous HBF₄ two-phase system affordedN-mono-,N-1,1-ferrocenylene-bis--alkylated, and 1,3-bis-ferrocenylalkylated tetrafluoroborates of the above-mentioned heterocyclic compounds in high yields. An X-ray structural study of 1,3-bis-(ferrocenylmethyl)benzotriazolium tetrafluoroborate confirmed unambiguously the 1,3-arrangement of the ferrocenylmethyl groups in the heterocycle.Translated fromIzvestiya Akademii Nauk.

Physical basis of the reactivity of carbonyl compounds

Summary By comparison of physical and chemical data an individual characteristic bonds it is shown that the chemical nature of these bonds is dependent on their physical state(the electron-nucleus interactions in them), which is manifested in the experimentally determined parameters of these bonds , E, and r. Taking carbonyl compounds as an example, we have shown that from the strictly correlated changes in these parameters in characteristic bonds it is possible to make an estimate, on an experimental basis, of the electron displacements in the bonds as factors determining the reactivities of these bonds and as factors expressing the structure of the molecule and the mutual effects of its atoms.     

The electronic structure of polyfluorinated carbonyl compounds and correlation with ir spectra and reactivity

Calculations of electronic structure, force constants and anharmonicity constants of the C-O valence vibration for a number of fluorinated ketones and ethers have been performed by the CNDO/SW and CNDO/2 methods. The change of association constants for these molecules with phenol is qualitatively explained. Anomalies in the IR spectra are studied, the role of direct fluorine - oxygen interactions is considered. The inductive constants for H(CF₂)₂, and C1(CF₂)₂, are calculated.

Conclusions The polarographic behavior and semi- and thiosemicarbazones of acetic, butyric, isobutyric, and isovaleric aldehydes and the thiosemicarbazone of propionaldehyde was studied.Translated from Izvestiya Akademii Nauk SSSR, Setiya Khimicheskaya, No. 6, pp. 978–984, June, 1964
