PH-ADDUCTS -- BIRADICALS -- TETRAAZAPHENANTHRENES
Аннотация: O- and C-Adducts of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium salts are latent sources of biradicals capable of forming tetraazaphenanthrene derivatives via dimerization. The mechanisms of the reactions were examined using ESR spectroscopy. The stereochemistry of the resulting heterocyclic systems was studied by NMR spectroscopy. The crystallographic data on their three-dimensional structures were obtained

    Unusual synthesis of triosmium carbene clusters by tandem activation of chlorohydrocarbons and heterocyclic amines / B. Y. Savkov, V. A. Maksakov, A. V. Virovets [et al.] // European journal of inorganic chemistry. - 2021. - № 10. - P989–996
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The carbene ligand is assembled on a cluster core of two dichloromethane and one morpholine at room temperature, which is the first example of carbene ligands formed in this way. Clusters with a carbene ligand exist as two stable isomers, as confirmed by NMR studies and conformational analysis. Possible mechanistic pathways for the formation of clusters with carbene and enamine ligands are proposed.

TEMPLATE SYNTHESIS -- CHALCONE PODAND -- CROWN ETHERS
Аннотация: A new type of intramolecular cyclization of 1,5-bis[2-(E-3-oxo-3-phenylprop-1-enyl)-phenoxy]-3-oxapentane with 3-aminotriazole promoted by potassium ions was discovered. A cascade mechanism for the formation of crownophane with 4,7-dihydro[1,2,4]triazolo[1,5-a]-pyrimidine fragment was suggested. Effects of oligooxyethylene fragment of the chalcone podand and acid-base catalysis on the selectivity of the cyclocondensation processes and degree of oxidation of triazolopyrimidine fragments were studied. The product structures were confirmed by IR, 1H and 13C NMR spectroscopy and X-ray diffraction study

The starting materials were prepared by the stereoselective reaction of ?-(trifluoroethylidene)nitroalkanes, which react with ethyl ?-morpholino- and ?-piperidinocrotonates at the more nucleophilic ?-position, whereas the reaction of ?-(trichloroethylidene)nitroalkanes proceeds at the ?-methyl group to give the corresponding linear products

CHITOSAN -- THIOCARBAMOYL CHITOSAN -- IONS OF GOLD(III)
Аннотация: Thiocarbamoyl chitosan (TCC) was synthesized by grafting thiourea on chitosan backbone in eutectic composition of ammonium thiocyanate—thiourea. Insoluble products with the amno group functionalization degree of 0.3–1.1 can be prepared by varying the conditions of polymer-analogous (synthesis in a gel) transformation. Structure of the synthesized chitosan derivatives was characterized by elemental analysis, diffuse reflectance infrared spectroscopy, and the solid state 13C NMR. Study of sorption properties of TCC shows high sorption capacity and selectivity for the ions of gold(III), platinum(IV), and palladium(II) as evidenced by results obtained at pH 2 in the presence of 100–1000-fold excess of iron(III), copper(II), zinc(II), and nickel(II). Sorption capacity of TCC for all ions increases with the increase in the degree of substitution and changes in the series: AuIII > PdII > PtIV
