Заглавие : (Mechano)synthesis of azomethine- and terpyridine-linked diketopyrrolopyrrole-based polymers
Место публикации : Chimica Techno Acta. - 2023. - Vol. 10, № 2. - С. 202310204

Ключевые слова (''Своб.индексиров.''): diketopyrrolopyrrole-based polymers--pd-catalyzed synthesis--mechanosynthesis
Аннотация: Three efficient synthetic approaches towards new azomethine- and terpyridine-containing 2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione (diketopyrrolopyrrole, DPP) based polymers, such as P1 and P2, are reported. The first approach involves the Pd-catalyzed synthesis via two- or three-component Suzuki or Stille cross-coupling reaction in solution. The second approach involves Pd-catalyzed Suzuki cross-coupling reaction under ballmilling conditions. And, finally, the third approach involves Pd-free condensation reaction under ball-milling conditions. The newly obtained polymers exhibited absorbance around 700 nm and emission around 900 nm, and, thus, these polymers are considered to be NIR-fluorophores.

Ключевые слова (''Своб.индексиров.''): nitrogen heterocycles --fluorine--oxygen heterocycles
Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

Ключевые слова (''Своб.индексиров.''): thieno[2,3-b]indole --dyes--thiophene
Аннотация: Two novel dyes IK-1,2 bearing the 8-alkyl-8H-thieno[2,3-b]indole unit as an electron-donating part of the push-pull system have been designed and prepared, as promising sensitizers for solar cells. The key steps of the synthesis involve the crotonic condensation of 1-alkylisatins with 2-acetylthiophene, followed by reduction of the C=C double bond and further cyclization through the Paal-Knorr reaction with the Lawesson reagent, thus leading to the formation of 2-(thien-2-yl) substituted thieno[2,3-b] indole derivatives. The optical and electrochemical properties of these dye's have been investigated by using spectrophotometry and cyclic voltammetry respectively, while their photovoltaic performance was evaluated by a device fabricatien study. The DSSCs based on IK-1 and IK-2 have demonstrated an efficiency of eta = 0.37% (FF = 73%) and eta = 0.7g% (FF = 69%) under 100 mW cm(-2) simulated AM 1.5G solar irradiation, respectively.

Ключевые слова (''Своб.индексиров.''): aldol-crotonic condensation --lawesson's reagent--isatin
Аннотация: A short and robust approach for the synthesis of 2-(hetero)aryl substituted thieno[2,3-b]indoles from easily available 1-alkylisatins and acetylated (hetero)arenes has been advanced. The two-step procedure includes the "aldol-crotonic" type of condensation of the starting materials, followed by treatment of the intermediate 3-(2-oxo-2-(hetero)arylethylidene) indolin-2-ones with Lawesson's reagent. The latter process involves two sequential reactions, namely reduction of the C=C ethylidene double bond of the intermediate indolin-2-ones followed by the Paal-Knorr cyclization, thus affording tricyclic thieno[2,3-b]indoles.

Аннотация: Azaheterocyclic derivatives of 1,2-dicarba- closo -dodeca borane (ortho -carborane) are known to be of particular interest due to numerous plausible applications, particularly, in medicine, materials science, and advanced technologies. Three principal synthetic strategies resulting in azaheterocyclic carboranes, in which boron-enriched and azaheterocyclic fragments are linked to each other, either directly by means of the C-C bonds or through a short spacer (CH 2, CH 2 S, CH 2 O, etc.), have been outlined. These synthetic approaches are of general character and can be used both individually and in combination to afford promising organoboron clusters of diverse architectures. 1 Introduction 2 C-C Cross-Coupling Strategies in the Synthesis of Azahetero cyclic Carboranes 3 Carboryne-Based Transformation Strategies 4 Condensation Strategies: Reactions of Decaborane B 10 H 14 with Substituted Acetylenes 5 Conclusion and Outlook.

Заглавие : Bioactive silicon-iron-containing glycerohydrogel synthesized by the sol-gel method in the presence of chitosan
Место публикации : Russian chemical bulletin. - 2022. - Vol. 71, № 11. - С. 2342-2351
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A novel biologically active nanocomposite glycerohydrogel based on two biocompatible precursors, silicon and iron glycerolates, was synthesized by the sol—gel method in the presence of chitosan (Ch). The composition and structural features of the gel were characterized by advanced analytical methods including transmission electron microscopy, X-ray diffraction, and atomic emission spectroscopy. It was shown that iron(iii) monoglycerolate undergoes partial hydrolysis under the gelation conditions and exists as a separate nanoscale phase along with the hydrolysis products in cells of the 3D Si-containing polymeric gel network. This network is formed as a result of incomplete hydrolysis of silicon glycerolates in excess glycerol followed by homo- and heterofunctional condensation of silanol groups with the formation of Si-O-Si units containing residual glyceroxy groups at the silicon atom. Chitosan forms numerous intermolecular bonds with the 3D gel network, accelerates the process of gelation, makes the gel morphostructure more ordered, and increases the stability of the gel. The Si-Fe-Ch-containing glycerohydrogel is nontoxic and possesses hemostatic and wound-healing activity, being a promising topical medication for medical and veterinary practice.

Аннотация: 1H and 29Si NMR spectroscopy showed that the product of the reaction of dimethyldiethoxysilane with glycerol in the molar ratio 1: 2 is an equilibrium mixture of dimethyldiglyceroxysilane and low-molecular-weight condensation products. The change of viscosity of silicon dimethylglycerolates, synthesized using different excesses of glycerol, versus time was studied by viscosimetry. Composition of products of hydrolysis and condensation of silicon dimethylglycerolates is determined by their concentration in the starting aqueous solutions

Заглавие : Condensation of 2-polyfluoroacycloalkanones with aldehydes and dimethylformamide-dimethylacetal

Аннотация: Polyfluorinated 1,3-diketones containing carbocycles react with aldehydes under Lewis-acid catalysis and also with dimethylformamide-dimetylacetal without catalysis, yielding exclusively (E)-configured condensation products involving the methylene group of the carbocycle. Novel trifluoromethylated chromenes are prepared from 2-trifluoroacetylcycloalkanones and salicylaldehyde. The structures of two new compounds, 2-(E)-benzylidene-6-trifluoroacetylcyclohexanone and 4-trifluoroacetyl-2,3-dihydro-1H-xantene, are confirmed by X-ray structure analysis.
