    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.

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

    Role of polar solvents for the synthesis of pillar[6]arenes [Electronic resource] / S. Santra, I. S. Kovalev, D. S. Kopchuk, G. V. Zyryanov, A. Majee, V. N. Charushin, O. N. Chupakhin // RSC Advances. - 2015. - Vol. 5, № 126. - С. 104278-104282. - Bibliogr. : p. 104282 (26 ref.)

Аннотация: An efficient procedure for the synthesis of pillar[6]arenes has been developed. The procedure involves the condensation of 1,4-dialkoxybenzenes and paraformaldehyde in the presence of a catalytic amount of H2SO4 or BF3 center dot OEt2 in polar solvent media (acetonitrile, ethyl alcohol, acetone etc.). In all cases the interaction afforded pillar[6]arenes in high yields.

    Polyfluorosalicylic acids as ligands for the creation of bioactive metal complexes / E. V. Shchegolkov, I. V. Shchur, Y. V. Burgart, V. I. Saloutin // AIP conference proceedings. - 2022. - Vol. 2390. - Ст. 020076

LIGANDS
Аннотация: The reactions of copper(II) and cobalt(II) mixed complexes based on methyl trifluorosalicylate and 2,2’-bipyridine and 1,10-phenanthroline with 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) as the Lewis acid were investigated. In the case of copper(II) complexes, the hydrolysis of ester fragment occurred to form heteroligand complexes of trifluorosalicylic acid and bipyridine-like ligand associated with fluorinated alcohol. The structure of complexes corresponded to [Cu(L3-H2)(bipy or phen)*(HFIP), L3 −trifluorosalicylic acid]. In contrast, cobalt(II) complexes in refluxing HFIP resulted in the complexes [Co(L1-H)2(bipy or phen)*(HFIP), L1 – methyl trifluorosalicylate], in which the ester ligand was preserved.

    Opening of the 1,3,5-triazine ring in 3-methyl-5-(trinitromethyl)tetrazolo[1,5-a][1,3,5]triazin-7-one by the action of alcohols / V. V. Bakharev, A. A. Gidaspov, V. A. Zalomlenkov [et al.] // Chemistry of Heterocyclic Compounds. - 2022. - Vol. 58. - P153–158
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: It was shown for the first time that in the reaction of 3-methyl-5-(trinitromethyl)tetrazolo[1,5-a][1,3,5]triazin-7-one with alcohols in the presence of bases, along with the expected substitution of the trinitromethyl group, opening of the 1,3,5-triazine ring with the addition of an alcohol at the site of the C–N bond cleavage takes place. It was found that in the absence of bases only opening of the 1,3,5-triazine ring occurs with the formation of alkyl esters of {1-[(1-methyl-1H-tetrazol-5-yl)imino]-2,2,2-trinitroethyl}carbamic acid, and the trinitromethyl group retains high reactivity and can be substituted by the action of alcohols in the presence of a base.
