S 10 S-N(H) reactions of 1,2,4-triazine N-oxides, pyrazine N-oxides, and pterin N-oxides with arenethiols [Electronic resource] / D. N. Kozhevnikov, I. S. Kovalev, V. L. Rusinov, O. N. Chupakhin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2001. - Vol. 50, № 6. - P1068-1071 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: 1,2,4-Triazine 4-oxides were found to enter into the reactions of nucleophilic substitution of hydrogen with S-nucleophiles (arenethiols) in the presence of acylating agents and trifluoroacetic acid. The reactions proceeded with loss of the N-oxide function to form 5-arylthio-1,2,4-triazines. 2-Amino-3-ethoxycarbonylpyrazine 1-oxides and 2-amino-4-oxopterin 8-oxides react with arenethiol analogously \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2001, 50 (6), 1068.pdf |
