Аннотация: Magnetic particles Fe@C were chemically modified with dibenzo-18-crown-6, dibenzo-21-crown-7 and dibenzo-24- crown-8 through the C-C bond formation using diazonium salts of the corresponding crown ethers. It has been shown that the ability of Fe@C-dibenzocrown ether composites for sorbtion of Yb3+ cations from 0.1 M hydrochloric acid solutions increased from 0 to 90.9-100 %, relative to dibenzocrown ether

CHITOSAN -- SORBENT -- GOLD(III)
Аннотация: A novel method for the synthesis of a hetaryl containing chelate amino polymer, namely, N (4(5) imidazolylmethyl)chitosan (IMC), with a degree of substitution up to 0.3 was pro posed. The "synthesis in gel" approach involves direct substitution of the hydroxyl group in 4(5) imidazolylmethanol. The structures of these polymers were confirmed by 1H NMR data. For sorption studies, IMC samples were crosslinked with epichlorohydrin and diglycidyl ethers of ethylene glycol and diethylene glycol. The degrees of swelling and sorption properties of the polymers largely depend on the crosslinking agent and the degree of crosslinking. The sorption capacities of IMC for AuIII, PtIV, and PdII ions are higher than those of the nonmodified polymer. The extraction of noble metal ions from chloride solutions becomes more selective with increasing degree of crosslinking. The sorption capacity of IMC for CoII and NiII ions is higher than those of chitosan and its known N heterocyclic derivatives

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

Аннотация: Epoxy-anhydride polymers based on N,N,O-triglycidyl-p-aminophenol and isomethyltetrahydrophthalic anhydride were synthesized in the presence of new active modifiers, polyfluoroalkyl glycidyl ethers. The kinetics of the reactions of the modifiers with the anhydride were studied by differential scanning calorimetry and IR spectroscopy. The physicomechanical characteristics, glass transition points, and water absorption of the polymers were determined.

Аннотация: 3-Nitro-2-trifluoro(trichloro)methyl-2H-chromenes undergo heterodiene cycloaddition to 2,3-dihydrofuran and ethyl vinyl ether under solvent-free conditions producing novel cyclic nitronates with high stereoselectivity and in good yields. 3,6-Dinitro-2-trifluoromethyl-2H-chromene reacts with two molecules of ethyl vinyl ether to give the tandem [4+2]/[3+2] cycloaddition adduct in 48% yield. The stereochemistry of the products was established based on 2D COSY, NOESY, HSQC, and HMBC experiments and an X-ray diffraction study
