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

Аннотация: Nucleophilic substitution of hydrogen in pyrazine N-oxides under the action of CH-active compounds requires activation with acylating agents. This activation facilitates aromatization of intermediate H adducts via elimination of the acid residue to form substituted pyrazines. More electrophilic 1,2,4-triazine 4-oxides react with carbanions derived from CH-active compounds without additional activation according to a scheme, which has previously been unknown for azine N-oxides. This scheme involves aromatization of H adducts through elimination of water by the E1cb mechanism. The reaction products occur in DMSO-d6 solutions predominantly as 6-methylene-1,6-dihydropyrazines and 5-methylene-4,5-dihydro-1,2,4-triazines.??nucleophilic substitution of hydrogen - 1,2,4-triazine 4-oxide - pyrazine 1-oxide - carbanion - CH-active compounds??

Аннотация: The N-oxides of azines 1a–g react with lithium and/or potassium acetylides to give the corresponding ethynylazines 2a–g. Reaction with lithium acetylide requires subsequent acylation of the intermediate anionic adduct for rearomatization whereas in the case of potassium acetylide, auto-aromatization takes place??

    CuCl2 induced reactions of 6-ethynyl- and 6-cyano-5-aryl-2,2-bipyridines with various N- and O-nucleophiles in comparison with the reactions of relative 1,2,4-triazines [Text] / A. M.

Аннотация: Meanwhile 5-aryl-6-cyano-2,2-bipyridines are very stable towards various nucleophiles, addition copper(II) chloride to the reactional mixture facilitates nucleophilic addition to the cyano group dramatically. The cyanobipyridines react easily with water, methanol, ethanolamine in the presence of CuCl2 yielding well-crystallized complexes containing carboxylates, carboximidates or carboxamidines as ligands. 5-Cyano-1,2,4-triazines are more active in the reactions due to higher electron-withdrawing properties of this heterocycle. Due to the same reason acetylene moiety of 5-ethynyl-3-pyridyl-1,2,4-triazine adds water quite easily but in the presence of copper chloride as well

    Phosphorescence vs Fluorescence in Cyclometalated Platinum(II) and Iridium(III) Complexes of (Oligo)thienylpyridines / D. N. Kozhevnikov, V. N. Kozhevnikov, M. Z. Shafikov, A. M. Prokhorov, D. W. Bruce, J. A. Gareth Williams // Inorganic Chemistry . - 2011. - Vol. 50, № 8. - С. 3804-3815

OLIGOTHIENYLPYRIDINES -- LIGANDS -- LUMINESCENCE PROPERTIES
Аннотация: Two newly prepared oligothienylpyridines, 5-(2-pyridyl)-5?-dodecyl-2,2?-bithiophene, HL2, and 5-(2-pyridyl)-5??-dodecyl-2,2?:5?,2??-ter-thiophene, HL3, bind to platinum(II) and iridium(III) as NC-coordinating ligands, cyclometallating at position C4 in the thiophene ring adjacent to the pyridine, leaving a chain of either one or two pendent thiophenes. The synthesis of complexes of the form [PtLn(acac)] and [Ir(Ln)2(acac)] (n = 2 or 3) is described. The absorption and luminescence properties of these four new complexes are compared with the behavior of the known complexes [PtL1(acac)] and [Ir(L1)2(acac)] {HL1 = 2-(2-thienyl)pyridine}, and the profound differences in behavior are interpreted with the aid of time-dependent density functional theory (TD-DFT) calculations. Whereas [PtL1(acac)] displays solely intense phosphorescence from a triplet state of mixed ??*/MLCT character, the phosphorescence of [PtL2(acac)] and [PtL3(acac)] is weak, strongly red shifted, and accompanied by higher-energy fluorescence. TD-DFT reveals that this difference is probably due to the metal character in the lowest-energy excited states being strongly attenuated upon introduction of the additional thienyl rings, such that the spin?orbit coupling effect of the metal in promoting intersystem crossing is reduced. A similar pattern of behavior is observed for the iridium complexes, except that the changeover to dual emission is delayed to the terthiophene complex [Ir(L3)2(acac)], reflecting the higher degree of metal character in the frontier orbitals of the iridium complexes than their platinum counterparts.??

Аннотация: Pyrimidine 1-oxides with cyanamide afforded 2-ureidopyrimidines as the result of the nucleophilic substitution of hydrogen, whereas the formation of similar 2-trichloroacetylaminopyrimidines occurs as dipolar 1,3-cycloaddition of the same oxides to trichloroacetonitrile under much more drastic conditions and in lower yields??
