S 98 Synthesis of trifluoroalkyl- and fluoroaryl-substituted 4,5-dihydro-1H-1,2,4-triazole-5-thiones [Electronic resource] / E. B. Vasil'eva, D. V. Sevenard, O. G. Khomutov, O. A. Kuznetsova, N. S. Karpenko, V. I. Filyakova // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2004. - Vol. 40, № 6. - P874-878. - Библиогр. : с. 878 (8 назв.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Reactions of 4-(4-fluorophenyl)-, 4-(4-trifluoromethoxyphenyl)-, 4-(3,4-difluorophenyl)-, 4-(4-trifluoromethylphenyl)-, 4-piperidino-, and 4-(3-pyridyl)thiosemicarbazides with esters gave the corresponding 3,4-disubstituted 4,5-dihydro-1H-1,2,4-triazole-5-thiones and their S-alkyl derivatives. Analogous reactions with methyl 2,2,3,3,4,4,5,5-octafluoropentanoate and 2,2,3,3,4,4,5,5-octafluoropentanenitrile afforded, respectively, the acylation and addition products. \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2004, 40 (6), 874.pdf |
