ДИФОРМИЛФЕНОЛ -- ПОЛИДЕНТАТНЫЕ ОСНОВАНИЯ
Аннотация: [1+2] Condensation of 2,6-diformylphenol (1) with ethyl-2-[(2-aminophenyl)aminomethylidene]-1,3-dicarbonyl compounds (2) resulted in new macroacyclic bisazomethines 3 having 2-hydroxyphenyl spacer. They are capable of regulated selective modes of mono- and binuclear complexes 4, 5 with 3d metal ions in proper conditions. Crystal structure of 4d was confirmed with X-Ray data. A moderate tuberculostatic activity of Schiff base ligands 3c,d is reported

    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.

COPPER(II) -- DIKETONATES -- CYTOTOXIC ACTIVITY -- ANTIMICROBIAL ACTIVITY
Аннотация: Copper(II) complexes with 1,1,1-trifluoro-4-(4-methoxyphenyl)butan-2,4-dione (HL1) were synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single crystal X-ray diffraction. The biological properties of HL1 and cis-[Cu(L1)2(DMSO)] (3) were examined against Gram-positive and Gram-negative bacteria and opportunistic unicellular fungi. The cytotoxicity was estimated towards the HeLa and Vero cell lines. Complex 3 demonstrated antibacterial activity towards S. aureus comparable to that of streptomycin, lower antifungal activity than the ligand HL1 and moderate cytotoxicity. The bioactivity was compared with the activity of compounds of similar structures. The effect of changing the position of the methoxy group at the aromatic ring in the ligand moiety of the complexes on their antimicrobial and cytotoxic activity was explored. We propose that complex 3 has lower bioavailability and reduced bioactivity than expected due to strong intermolecular contacts. In addition, molecular docking studies provided theoretical information on the interactions of tested compounds with ribonucleotide reductase subunit R2, as well as the chaperones Hsp70 and Hsp90, which are important biomolecular targets for antitumor and antimicrobial drug search and design. The obtained results revealed that the complexes displayed enhanced affinity over organic ligands. Taken together, the copper(II) complexes with the trifluoromethyl methoxyphenyl-substituted β-diketones could be considered as promising anticancer agents with antibacterial properties

CHIRAL AZINYLFERROCENES -- CROSS-COUPLING REACTION -- HALOGENATED AZINES
Аннотация: Two synthetic routes to the chiral azinylferrocenes (CAFs) 5 and 15, key intermediates for the synthesis of new enantiomerically enriched P,N-ligands, have been compared. The first approach is based on the palladium-catalyzed cross-coupling reaction of halogenated azines with organozinc derivatives of ferrocenes (the Negishi reaction). The second approach exploits a new synthetic methodology, which provides a shorter pathway, through the direct C–H functionalization of aromatics by the C–C coupling of halogen-free (hetero)arenes with lithium ferrocenes bearing stereogenic C and S atoms. The palladium complexes of P,N-ligands have been used as catalysts for the Tsuji–Trost reaction, which proceeds with high enantioselectivity to give allylic substitution products in good yields.

1,2,4-TRIAZINE -- LIGANDS -- SYNTHESIS
Аннотация: The ‘triazine’ methodology for the synthesis of functionalized pyridine ligands proved to be a convenient method for the preparation of a luminescent Pt(II) complex. The key ligand can be assembled easily starting from readily accessible reagents. Further cycloplatination and post-functionalization led to the ready-to-go luminescent ‘tag’ 2 for peptide labeling

    The synthesis of aminophenyl-substituted 2,2′-bipyridine ligands by “1,2,4-triazine” methodology / A. P. Krinochkin, D. S. Kopchuk, M. I. Savchuk [et al.] // AIP Conference Proceedings. - 2021. - Vol. 2388, № 1. - Ст. 030016
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A convenient synthetic approach to the 2,2’-bipyridines, including those with a condensed cyclopentene fragment, having an aminophenyl substituent at the C5 or C6 positions is reported. The products were obtained via their 1,2,4-triazine analogs with a nitro group, by the subsequent transformation of their 1,2,4-triazine ring into a pyridine one and the reduction of the nitro group to the amino group.

DINUCLEAR COMPLEXES -- SPIN MAGNETISM -- TETRAZINES
Аннотация: Dinuclear complexes of CuII with 3-(3,5-dimethylpyrazol-1-yl)-6-(2-hydroxyethylami-no)-1,2,4,5-tetrazine (1) and CoII with 3-(3,5-dimethylpyrazol-1-yl)-6-(piperidin-1-yl)-1,2,4,5- tetrazine (2) were synthesized and structurally characterized, and the magnetic (SQUID) and resonance (EPR) properties of van der Waals crystals based on these complexes were studied. Unusual behavior of the effective magnetic moment ?eff(T) is observed at T < 60 K. A nonmonotonic increase in eff() for 1 (s~6 %) and a 20% reduction of eff for 2 have a common origin and are due to the influence of spin-orbital coupling on the character of the splitting between the t2g and eg levels of the central ion. Distortions of the coordination site “switch on” a positive (1) or negative (2) contribution of the orbital magnetic moment near 6 K. Irreversible temperature behavior of eff(T) in the heating and cooling regimes in the vicinity of 60 K suggests that the character of structural distortions and the magnetic properties are related to ligand geometry. This factor plays a significant role in crystal engineering of magnetoactive structures with polynitrogen ligands
