Аннотация: The new N,N,O-ligand 6-phenyl-3-(2-pyridyl)-5-(trifluoroacetylmethylidene)-4,5-dihydro-1,2,4-triazine (L) was synthesized, and its complex with CuII was prepared. The structure of the complex was established by X-ray diffraction. Magnetic measurements and ESR studies were carried out. Ab initio calculations of the electronic structure, exchange interactions, and the effective magnetic moment were performed. The intrastack polarization effect between the ? states of 1,2,4-triazine and the d states of copper was revealed and numerically validated

Аннотация: 1,2,4-Triazine 4-oxides were found to enter into the reactions of nucleophilic substitution of hydrogen with S-nucleophiles (arenethiols) in the presence of acylating agents and trifluoroacetic acid. The reactions proceeded with loss of the N-oxide function to form 5-arylthio-1,2,4-triazines. 2-Amino-3-ethoxycarbonylpyrazine 1-oxides and 2-amino-4-oxopterin 8-oxides react with arenethiol analogously

    1,2,4-Triazine method of bipyridine ligand synthesis for the preparation of new luminescent Eu(III) complexes [Text] / A. M. Prokhorov, V. N. Kozhevnikov, D. S. Kopchuk, D. N. Kozhevnikov // Tetrahedron. - 2011. - Vol. 67, № 3. - P597-607

Аннотация: The ‘triazine’ methodology for the synthesis of functionalised bipyridine ligands proved to be a convenient method for the preparation of luminescent Eu(III) complexes. The approach allows flexible construction of chromophore and coordination sphere with control of photophysical properties. Europium (III) complexes [Eu1]-[Eu5] prepared in this way exhibit intense long-life metal-centered luminescence in aqueous media. The aromatic substituent in the position 5 of bipyridine has a significant influence on luminescence parameters and is used to introduce functionality for bioconjugation. The complexes [Eu4] and [Eu5] bearing primary amine groups are ready-to-go luminescent ‘tags’ for peptide labeling

Аннотация: The basicity of some 1,2,4-triazine 4-oxides was estimated on a quantitative level, and their probable protonation patterns were ascertained. The dissociation constants of mono- and diprotonated 3-R-6-phenyl-1,2,4-triazine 4-oxides in aqueous buffer solutions and aqueous sulfuric acid solutions were determined (6-phenyl-1,2,4-triazine 4-oxide: pKBH + = 1.1, pKBH 2+ = - 6.02). According to the results of DFT calculations (B3LYP/6-311**) and spectral data, first protonation of 1,2,4-triazine 4-oxides involves the N1 nitrogen atom, and the second proton adds to the N-oxide oxygen a

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

Аннотация: On interacting α-bromoacetophenones with aromatic carboxylic acid hydrazides, the formation of two reaction products was observed in certain cases, the expected 1,2,4-triazine and the phenylglyoxal dihydrazone as an unexpected product. The effect of substituents in the initial substrates and of the conditions of carrying out the synthesis on the direction of the reaction have been studied
