POLYCHLORINATED BIPHENYLS -- SOVOL MIXTURE -- NUCLEOPHILIC SUBSTITUTION
Аннотация: In order to comprehend the data on reactivity of polychlorinated biphenyls of the Sovol mixture in nucleophilic substitution reactions we have performed quantum-chemical simulation using the RB3LYP\6-31G(d) gas phase approximation. Using the "Atoms-in-Molecules" approach, we have computed charges on the biphenyl carbon atoms adjacent to chlorine; furthermore, absolute chemical hardness and global electrophilicity index have been determined for the studied chlorobiphenyls. The calculated descriptors have been correlated with experimentally determined reactivity of the biphenyls in the hard acid-hard base nucleophilic reactions. The higher reactivity of more chlorinated substrates has been confirmed

CONGENERS -- DESCRIPTORS -- ELECTROPHILIC SUBSTITUTION
Аннотация: To explain the chemical reactivity of polychlorinated biphenyls in nucleophilic (SN) and electrophilic (SE) substitutions, quantum chemical calculations were carried out at the B3LYP/6-31G(d) level of the Density Functional Theory in gas phase. Carbon atomic charges in biphenyl structure were calculated by the Atoms-in-Molecules method. Chemical hardness and global electrophilicity index parameters were determined for congeners. A comparison of calculated descriptors and experimental data for congener reactivity in the SN and SE reactions was made. It is shown that interactions in the SN mechanism are reactions of the hard acid-hard base type, these are the most effective in case of highly chlorinated substrates. To explain the congener reactivity in the SE reactions, correct descriptors were not established. The obtained results can be used to carry out chemical transformations of the polychlorinated biphenyls in order to prepare them for microbiological destruction or preservation

HYDROGEN-BONDED BRIDGES -- RAY CRYSTAL-STRUCTURE -- SCHIFF-BASE LIGAND
Аннотация: A comparative analysis of the structures of copper(II) and nickel(II) chelate complexes with N-substituted 2-aminoethanols, 3-aminopropan- 1 -ols, glycines and beta-alanines is performed. It is shown that tetradentate ligands based on 3-aminopropan- 1 -ol and P-alanine, sterically hindered 2-aminoethanol derivatives and tridentate enamino ketone derivatives tend to form oligonuclear copper(II) and nickel(II) complexes. Glycine derivatives do not provide the formation of oligonuclear copper(II) and nickel(II) complexes. The magnetic properties of a number of polynuclear complexes are compared.

LUBRICATING COMPOSITIONS -- TRIBOENGINEERING PROPERTIES -- STEEL SURFACES
Аннотация: It is demonstrated that the wear rate of tribocouples can be reduced significantly with the use of lubricating compositions obtained by added super- and nanodispersed zinc or Cu-Sn powders to the Lithol-24 plastic grease. When the superdispersed powders of copper alloys interact with tribosurfaces, the copper and tin diffuse into the base metal, producing secondary composite superdispersed structures. The alloyed elements penetrate into the base metal more deeply if the powder contains the nanodispersed fraction. The films of polyfluorinated oligomers based on particles of zinc and copper alloy powders with functional substitutes reduce substantially the friction coefficient of kinematic couples when they are lubricated with these lubricating compositions and expand the temperature range of application of plastic greases

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

HOFMEISTER SERIES -- TITANIUM–GLYCEROL HYDROGELS -- SCHULTZE–HARDY RULE
Аннотация: Formation of organic/inorganic hydrogels based on silicon– and titanium–glycerol precursors synthesized by transesterification of alkoxy derivatives in excess of glycerol was investigated. The precursors in excess of glycerol and obtained gels were studied by chemical and physical methods including gelation kinetics, IR spectroscopy, XRD, dynamic and electrophoretic light scattering, mechanical deformation, which disclosed the basic difference in the gelation mechanism and structure of network in the hydrogels. Due to this difference, the gelation time of silicon– and titanium–glycerol precursors depended on pH or electrolyte addition in an opposite way. In the wide pH range, silicon–glycerol hydrogel was a polymeric single-phase system formed by the polymeric network homogeneously swollen in liquid water/glycerol medium. Flory–Rehner theory applied to the elastic modulus of these gels gave 40–180 monomer base units in the subchains of the network depending on water content in the gel. The mechanism of networking was three-dimensional polycondensation promoted by the electrically charged functional groups attached to the flexible polymeric chains. Electrolyte solutions provided the gelation according to Hofmeister series. Titanium–glycerol hydrogels were heterogeneous colloid systems at pH > 1.5 and single-phase polymeric gels at lower pH. Electrolyte solutions provided the gelation according to Schultze–Hardy rule

ALFA,BETA- ALKENENITRILES -- A-SECO-TRITERPENOIDS -- ALLOBETULONE
Аннотация: A-seco-triterpenoids with a methylketone group were synthesized from epimeric 3-hydroxy-3-methyl-1-cyano-2,3-seco-triterpenoids of the lupane and 19β,28-epoxy-18αH-oleanane types, which were formed by a Grignard reaction. The resulting methylketones underwent under base-catalysis conditions an intramolecular cyclization to form A-pentacyclic β-substituted alkenenitriles. The synthesized compounds included 3-methyl-1-cyano-19β,28- epoxy-2,3-seco-2-nor-18αH-olean-3-one and methyl 3-methyl-1-cyano-2- norlup-1(3),20(29)-dien-28-oate, which inhibited in vitro reproduction of human immunodeficiency virus type 1.
