[en] The mono- and intramolecular cation-radicals (CR) reactions of diethylmercury in the CFCl3, CFCl2CF2Cl matrices and CF2BrCF2Br and CFCl3 freons vitrified mixture (1:1) were studied through the EPR method. Formation of radical products of transformations of the initial CR diethylmercury (X-ray radiation dose - 100-200 Gy at the temperature of 293 K) was studied through the spin trap of 2.4.6 - tri-tret-butylnitrosebenzene

[en] Electrochemical and chemical oxidation of 1,3,1',3'-tetramethyl-2,3,2',3'-tetrahydro-2,2'-dipyriminyl takes place with rupture of the C-C bond in the initially formed cation radical. In the oxidation of the compound with aluminum chloride in nitrobenzene, ESR revealed a cation radical with an unresolved hyperfine structure. Oxidation of the dihydrodimer with nitrosonium perchlorate in nitrobenzene or nitromethane resulted in the same spectra. Cyclic volt-ampere diagrams are included

[en] Hydrogen sulfide radical cation was generated by electrochemical method during γ-radiation in freon matrix induced by one-electron oxidants (spatially hindered o-benzoquinones). According to ESR spectroscopy data H2S+. radical cation is extremely unstable, even ata temperature of 77 K in freon matrix it exists for 15 min at most. It is shown that hydrogen sulfide radical cation has the properties of a superacid

Проведено генерирование катион-радикала сероводорода электрохимическим методом, при γ-облучении во фреоновой матрице, под действием одноэлектронных окислителей (пространственно-затрудненных о-бензохинонов). По данным ЭПР спектроскопии катион-радикал H2S+. крайне нестабилен, даже при температуре не более 77 К во фреоновой матрице он существует не более 15 мин. Показано, что катион-радикал сероводорода обладает свойствами сверхкислотыJournal
