Аннотация: The synthesis of a series of push-pull aryl and arylethynyl 2-(thiophen-2-yl) quinazoline derivatives is presented. The photophysical properties of the newly generated compounds are also described. Functionalization of the (2-thienyl) quinazoline fluorophore at the 5'-position with aryl and arylethynyl moieties was performed using bromination and subsequent palladium-catalyzed cross-coupling reactions. Optical studies revealed that 4-(diethylamino) phenyl and 4-(diphen-ylamino) phenyl derivatives emit green light upon irradiation, whereas their 4-(9H-carbazol-9-yl) phenyl, methoxyphenyl, thienyl and arylethynyl counterparts are characterized by blue light emission capabilities. The effect of protonation has also been studied, and the ability of some of these molecules to function as colorimetric and luminescent pH sensors has been demonstrated with significant color changes and luminescence switching upon the introduction of acid.

    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.
