    Oximes of fluoroalkyl-containing 1,3-diketones: specific features of synthesis, analysis, and thermal stability / N. S. Boltacheva, P. A. Slepukhin, M. G. Pervova [et al.] // Russian chemical bulletin. - 2022. - Vol. 71, № 7. - P1464-1473
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Nitrosation of lithium 1,3-diketonates bearing fluoroalkyl and aryl (or hetaryl) substituents in positions 1 and 3 results in 3-polyfluoroalkyl-1,2,3-propanetrione 2-oximes (from this point on, oximes). Under similar conditions, lithium (Z)-1,1,1-trifluoro-4-oxo-4-(thien-2-yl)-2-buten-2-olate forms a hydration product of the corresponding oxime. Nitrosation of fluoroalkyl-containing lithium 1,3-diketonates is accompanied by retro-decomposition of the initial lithium 1,3-diketonates and the target oximes (or their hydration products) followed by oxidation and hydrolysis of the reaction products. Under the GC-MS conditions, the oximes undergo partial thermal decomposition to 2-aryl(hetaryl)-2-oxoethanenitriles. An analysis of solutions of the oximes in DMSO-d6 by 1H and 19F NMR spectroscopies revealed isomerization and hydration of these compounds. The temperature ranges of stability of the oximes were determined by thermogravimetric analysis and differential thermal analysis. The molecular and crystal structures of 4,4-difluoro-1-(4-methoxyphenyl)-1,2,3-butanetrione 2-oxime and 4,4,4-trifluoro-1-(thien-2-yl)-1,2,3-butanetrione 2-oxime were determined by X-ray diffraction.

Аннотация: Heating of NiCl2 · 6H2O with 10-fold excess of an oxime having an CH2 group (1–4) at 100 °C for 1 day in air leads to the formation of the dioxime/ato complexes [Ni(dioxime/ato)2] (5–8) formed due to a novel type of metal-mediated nitrosation. Compounds 5–8 were characterized by elemental analyses, FAB (5–7) or APCI (8) mass-spectrometry, IR, 1H and 13C{1H} spectroscopies (for 8), and X-ray structural study has been performed for 5 and 8; the corresponding ketones (9–12) were identified by LC–MS.
