Role of one-electron transfer in reactions with arylamines Место публикации : Chemistry of Heterocyclic Compounds. - 1977. - Vol. 13, № 5. - С. 562-566 Примечания : Bibliogr. : p. 566 (28 ref.) ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): n-methylazinium--benzoannelation effect--electrophilic cations Аннотация: A satisfactory correlation between the polarographic reduction potentials and the calculated energies of the lower vacant molecular orbitals was found for a number of N-methylazinium cations. The result of the aza effect and the benzoannelation effect is a shift of the reduction potentials to the positive region by 0.2-0.5 and 0.2-0.7 V, respectively. Electron transfer from N,N,N′,N′-tetramethyl-p-phenylenediamine to the most electrophilic cations was recorded. The possibility of the occurrence of reactions involving aminoarylation of the acridinium cation via a one-electron mechanism was demonstrated electrochemically and by model reactions Доп.точки доступа: Chupakhin, O.
