D 44 Deprotonation of pyrazole and its analogs by aqueous copper acetate in the presence of triethylamine / M. A. Yakovleva , E. V. Kushan, N. S. Boltacheva, V. I. Filyakova, S. E. Nefedov // Russian Journal of Inorganic Chemistry (Zhurnal Neorganicheskoi Khimii). - 2012. - Vol. 57, № 2. - С. 181-192 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): SECONDARY BUILDING UNITS -- MAGNETIC-PROPERTIES -- COORDINATION POLYMERS Аннотация: Deprotonation reactions of pyrazole and its analogs by aqueous copper acetate in benzene at room temperature in the presence of triethylamine were studied. Unlike 3,5-dimethylpyrazole, more acidic pyrazole, 5-methyl-3-trifluoromethylpyrazole, and 3,5-bis(trifluoromethyl)pyrazoles are deprotonated to give pyrazolate bridges. The structural features of the obtained compounds are discussed based on X-ray diffraction data \\\\Expert2\\nbo\\Russian Journal of Inorganic Chemistry\\2012, v. 57, N. 2, p.181-192.pdf |

Charushin // Russian Journal of General Chemistry. - 2012. - Vol.82, №8. - С. 1444-1450 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CHLOROFORM -- TRIFLUOROMETHYLPYRAZOLE -- TRIS(PYRAZOL-1-YL)METHANE Аннотация: Reaction of 3(5)-methyl-5(3)-trifluoromethylpyrazole (I) with chloroform leads to a complex mixture of compounds. The main components are {bis[(5-methyl-3-trifluoromethyl)pyrazol-1-yl](3-methyl-5-trifluoromethyl)pyrazol-1-yl}methane, bis{[(3-methyl-5-trifluoromethyl)pyrazol-1-yl](5-methyl-3-trifluoromethyl)-pyrazol-1-yl}methane, and tris[(3-methyl-5-trifluoro-methyl)pyrazol-1-yl]methane. The structure of isomeric substances was proved by XRD method \\\\Expert2\\nbo\\Russian Journal of General Chemistry\\2012, V. 82, N 8, p. 1444–1450.pdf |
