experimental part, p. 3483 - 3489 (2011/06/11)
(3,4-Dimethoxyphenyl)(2,3,4-trimethoxyphenyl)methanone was synthesized and its bromination was investigated in different conditions. Nine new products (bromophenol derivatives) were isolated in the reactions. These bromophenol derivatives were obtained by selective O-demethylation in its bromination with bromine. The products and their formations were discussed.
THE ESR SPECTRA, STRUCTURE, AND REACTIVITY OF AROMATIC RADICAL-CATIONS IN SUPERACIDS
Rudenko, A. P.
, p. 1946 - 1980 (2007/10/03)
The oxidation of aromatic compounds by lead dioxide in superacids based on fluorosulfonic acid at -75 deg C takes place by a one-electron mechanism and leads in many cases to relatively stable radical-cations.The ESR spectra, the isotropic hyperfine coupling constants, data on the reactivity of the radical-cations, and the structures of the final products from their transformations under "long-life" conditions are presented.
