Paragraph 0019, (2016/11/21)
The invention discloses a 4-(4-nitrophenyl)-4H-1,2,4-triazole copper complex monocrystal and applications thereof. The chemical structural formula of the monocrystal is [Cu2(L)(tba)](ClO4)2.CH3OH.H2O, wherein the L represents 4-(4-nitrophenyl)-4H-1,2,4-triazole, and the tba represents 4-(4H-1,2,4-triazole-4-yl)aniline. The invention also discloses a preparation method of the monocrystal. The preparation method adopts a room temperature volatilization technology, and comprises the following steps: adding L, tba, and Cu(ClO4)2.6H2O into water, stirring for an half hour, filtering, and volatilizing the filtrate at a room temperature for one week to obtain blue block-like crystals suitable for X-ray single crystal diffraction; wherein the mole ratio of Cu(ClO4)2.6H2O:tba:L is 1:1:1. The invention further discloses applications of the 4-(4-nitrophenyl)-4H-1,2,4-triazole copper complex monocrystal as a potential fluorescent material in the detection of adsorption amount of dyes or illuminating agent.

-
Paragraph 0019; 0020, (2016/12/12)
The invention discloses a 4-(4-nitrophenyl)-4H-1,2,4-triazole dimeric silver complex single-crystal, a preparation method therefor, and an application thereof. The structure is [Ag2(L)4](ClO4)2.0.5H2O, where L=4-(4-nitrophenyl)-4H-1,2,4-triazole. A normal temperature volatilization method is adopted. That is, AgClO4.6H2O and L are stirred in water for a half hour and then filtered, and filtrate is volatilized at normal temperature for a week to obtain a colorless blocky crystal suitable for X-ray single-crystal diffraction, wherein a mole ratio of AgClO4.6H2O to L is 1:1. The invention further discloses an application of a 4-(4-nitrophenyl)-4H-1,2,4-triazole dimeric silver complex in detection of the absorption quantity of a dye or an illuminating agent as a potential fluorescent material.

-
Page/Page column 48; 80-81, (2011/04/19)
Homogenous and heterogenous catalysts comprising 1,2,4-triazole ligands and transition metals are described. The catalysts can be used to catalyze the oxidation of hydrocarbons and other reactions. In particular, the catalysts can be used to catalyze the selective oxidation of methane to methanol and/or other C1 and C2 oxidation products under mild conditions. The catalysts can also be used to catalyze aziridation and the formation of aminoalcohols from alkenes and to catalyze the degradation of cellulosic substrates. Efficient methods of synthesizing the catalysts are described, as well.
Preparation and N-alkylation of 4-Aryl-1,2,4-triazoles

experimental part, p. 2278 - 2286 (2010/08/20)
Heating of N,N-dimethylformamide azine dihydrochloride {N-[(dimethylamino) methylene]-N,N-dimethylhydrazonoformamide dihydrochloride} with anilines in the absence of a solvent gave a range of 4-aryl-1,2,4-triazoles by direct transamination. Ortho-substituents were tolerated. Some triazoles were converted into symmetrically and nonsymmetrically substituted bistriazolium salts, one of which was converted into a dicopper complex.

, p. 417 - 425 (2007/10/02)
The reactions of some representative N-(nitrophenyl)azoles with boiling aqueous ethanolic potassium hydroxide solution gave the corresponding bis(azolyl)azoxybenzenes.It is deduced that, in these reactions, the N-attached azolyl groups concerned are acting as weak electron-withdrawing groups.The structure of 2,2'-bis(1'',2'',4''-triazol-1''-yl)azoxybenzene was determined in the solid state by X-ray crystallography.The monoclinic crystals belong to the space group P21/c with a 8.815(1), b 7.863(1), c 11.836(1) Angstroem, β 109.96(1) deg and Z 2.The structure was refined to an R index of 0.041 for 1172 observed terms.The midpoint of the exocyclic N=N bond lies on an inversion centre so that the azoxy oxygen is statistically distributed between two sites.The benzene ring atoms are coplanar to within experimental error, as are the triazole ring atoms, and the dihedral angle between the perpendiculars to the two rings is 35.3(3) deg.
