S 98 Synthesis of chelating polymer sorbents by using the S-N(H) methodology / A. V. Pestov, P. A. Slepukhin, Yu. G. Yatluk, V. N. Charushin, O. N. Chupakhin // Journal of Applied Polymer Science . - 2012. - Vol.125, №3. - С. 1970-1978 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): FUNCTIONALIZATION OF POLYMERS -- PHENOL -- X-RAY ANALYSIS Аннотация: The article describes a new synthetic approach to modify the structure of phenol-formaldehyde and resorcinol-formaldehyde resins, which enables one to functionalize a polymer matrix by using the S?NH (nucleophilic aromatic substitution of hydrogen) methodology. Direct heteroarylation of phenol (resorcinol) fragments in polymer chains with 1,2,4-triazine derivatives illustrates a new synthetic method in the polymer chemistry. The feature of this methodology is that it provides an opportunity to accomplish direct one-pot polymer transformations by incorporating of rather complicated chelating groups through the displacement of hydrogen in phenol moieties. It has been shown that in order to obtain chemically modified polymers on the basis of phenol-formaldehyde and resorcinol-formaldehyde resins with a high degree of substitution with chelating units, a polymer matrix has to react with 3-(pyridin-2'-yl)-1,2,4-triazin-5(2H)-one. Also, it has been found that polymer sorbents with a high selectivity can be obtained by using the template method. Targeted synthesis of model compounds, as structural units of the chelating polymers, and elucidation of the structure of their complexes with copper (II) ions have shown that the most plausible type of coordination is formation of the bridge 1 : 1 complexes of the a,a'-bipyridinyl type. \\\\expert2\\nbo\\Journal of Applied Polymer Science\\2012, vol.125,p.1970.pdf |
N 58 Nickel(II) and copper(II) complexes based on N-(2-Carboxyethyl) alkanolamines: Influence of the amino alcohol structure on the coordination sphere of the metal center [Electronic resource] / A. V. Pestov, P. A. Slepukhin, O. V. Koryakova, V. N. Charushin // Russian Journal of Coordination Chemistry. - 2014. - Vol.40, №4. - С. 216-223. - Bibliogr. : p. 223 (28 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): NICKEL(II) COMPLEXES -- ALCOHOL STRUCTURE -- ALKANOLAMINES Аннотация: New nickel(II) complexes based on N-(3-hydroxypropyl)-β-alanine, N-(bis(hydroxyme -thyl)methyl)-β-alanine, and N-(tris(hydroxymethyl)methyl) -β-alanine are synthesized, and their structures are studied by X-ray diffraction analysis. The coordination spheres of the nickel and copper metal centers in the condensed phase are compared for a series of N-substituted β-alaninate ligands with the regularly changed dentate mode. In the case of the copper(II) complexes, an increase in the size of the alkanolamine chelate ring or the number of hydroxymethyl groups provides the formation of achiral coordination struc -tures, whereas the structures of the nickel(II) complexes are independent of the size of the lkanolamine che -late ring or the number of hydroxymethyl groups, thus providing the formation of the complexes as racemic modifications \\\\expert2\\nbo\\Russian Journal of Coordination Chemistry\\2014, v. 40, N. 4, p.216.pdf |
P 49 Pestov, A. V. Copper and nickel chelate complexes with polydentate N,O-ligands: structure and magnetic properties of polynuclear complexes [Electronic resource] / A. V. Pestov, P. A. Slepukhin, V. N. Charushin // Russian Chemical Reviews. - 2015. - Vol. 84, № 3. - С. 310-333. - Bibliogr. : p. 331-333(182 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 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. \\\\expert2\\nbo\\Russian Chemical Reviews\\2015, V.84, N38, p. 310-333.pdf |
