Direct Introduction of CH22SMe Group in Aromatic Ring

Publikováno v: Russian Journal of Organic Chemistry. 39:1572-1575

Application as a reagent of an accessible methylthiomethyl acetate in a reaction carried out under two-phase conditions and electrophilic catalysis can become a promising procedure for preparation of methylthiomethyl-substituted arenes.

Phase-transfer catalysis in reactions of electrophilic aromatic substitution

Autor: O. I. Kachurin, A. P. Zaraiskii, N. A. Zaraiskaya, L. I. Velichko, N. M. Matvienko, Z. A. Okhrimenko

Publikováno v: Russian Chemical Bulletin. 44:1815-1821

Electrophilic substitution in aromatic compounds under conditions of phase-transfer catalysis is considered. Catalysts of phase transfer of electrophilic reagents are used; their efficiency and the mechanism of their action in organic solvent-water s

Electronic structure and spectral characteristics of trinaphthodifuryls

Autor: Yu. B. Vysotskii, Ya. V. Zaikovskaya, O. I. Kachurin, L. I. Velichko

Publikováno v: Theoretical and Experimental Chemistry. 31:180-183

The diamagnetic susceptibilities, proton chemical shifts, and lowest singlet—singlet transition energies were calculated for trinaphthodifuryls. The calculated and experimental UV, PMR, and mass spectral data were analyzed to indicate the isomer mi

Autor: I. B. Frolova, O. I. Kachurin

Publikováno v: Russian Journal of Applied Chemistry. 74:74-76

Kinetics of formation of potassium carbazolate in the system liquid-solid, catalyzed with 18-crown-6, was studied. Applicability of the previously proposed macrokinetic model to this process was demonstrated.
