Oxidative transformations of 2-dialkylaminomethyl-4,6-di-tert-butylphenols depend on the nature of the oxidant, the character of the substituents at the nitrogen atom, and the medium.
A mechanism of the oxidation of these compounds is suggested. The molecular structure of the compound obtained as a result
of oxidative trimerization of 2-dimethylaminomethyl-4,6-di-tert-butylphenol was established by X-ray structural analysis.

It was established by the methods of 1H and 13C NMR spectroscopy that the oximohydrazones and bis(hydrazones) of aroylacetic aldehydes exist in the form of the corresponding 5-hydrazino- and 5-hydroxyamino-3-aryl-2-pyrazolines and -2-isoxazolines. The features of the aromatization of these compounds to the corresponding pyrazoles and isoxazoles were studied. Data on the mass-spectral study of the 5-hydroxyamino-2-pyrazoline-5-hydrazino-2-isoxazoline tautomerism in the gas phase are presented.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 927–935, July, 1989. 相似文献

Radiation-chemical transformations of chloride solutions in the presence of iodide additives were studied by pulse radiolysis.
Radical anion Cl2
⋅− oxidize I− ion, while in the secondary reactions Cl2 reacts with I− to form a mixed trihalide ion ICl2
−. A reaction model that satisfactorily describes the experimental data was proposed.

The radiation-chemical reduction of Ru(III) is studied in aqueous RuCl3 solutions containing isopropyl alcohol. In the presence of sodium polyacrylate, the stable sols of metal are formed with spherical particles 4–8 nm in diameter. The optical spectrum of nanoparticles is characterized by an increasing absorption in the UV spectral region with no maximum (200 = 7.2 × 1030 l mol–1 cm–1). The colloids of ruthenium in an aqueous solution are stable in the open air. 相似文献
