Abstract
A number of hitherto unknown trifluorinated beta-diketone oxymes were obtained by direct nitrosation with sodium nitrite in an acidic medium. 4,4,4-Trifluoro-2-(hydroxyimino)-1-(thiophene-2-yl)butane-1,3-dione and 4,4,4-trifluoro-2-(hydroxyimino)-1-phenylbutane-1,3-dione have been characterized by various physicochemical methods. The structure of the formed compounds was confirmed using FTIR, UV-visible spectroscopy, NMR and GC-MS. The spectral characteristics of the obtained compounds were modeled using DFT and TD-DFT calculations.
