The title coordination polymer, [CdBr(2)(C(8)H(8)N(4))(2)](n), arose from a layer-separated diffusion synthesis at room temperature. The title compound is isotypic with the I and Cl analogues. The Cd atom, located on an inversion center, is coordinated by two bromide ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CdBr(2)N(4) octa-hedral arrangeme...

The elaboration of a 6,6-spiroacetal scaffold to incorporate a triazole unit as a peptide bond surrogate at the anomeric position is described. The novel spiroacetal-triazole hybrid structures were generated via cycloaddition of a spiroacetal azide to a series of alkynes. The spiroacetal framework was constructed via Barbier reaction of bromide 10 with Weinreb amide 11, followed by acid-catalys...

The title compound, C 11H12N4O2,was prepared via the transformation of sodium 4-acetyl-1-phenyl-1H-[1.2.3]triazolate under the action of meth-oxy-amine hydro-chloride. The dihedral angle between the triazole and phenyl rings is 25.12 (16)° and the C atom of the meth-oxy group deviates from the triazole plane by 0.894 (4)Å. The conformation of the CONHR-group is consolodated by an intra-molecula...

The title coordination polymer, [CuCl(2)(C(8)H(8)N(4))(2)](n), arose from a layer-separated diffusion synthesis at room temperature. The Cu atom (site symmetry ) is coordinated by two chloride ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CuCl(2)N(4) octa-hedral arrangement. The bridging 1-(4-pyridylmeth-yl)-1H-1,2,4-triazole ligands [dihedral a...

In recent years, Triazole derivatives have acquired conspicuous significance due to their wide spectrum of biological activities. There is an increasing demand for the preparation of new antimicrobial agents due to the developing resistance towards conventional antibiotics. This review article covers the latest information over active triazole derivatives having different pharmacological action...

A reaction of equimolar equivalents 1-(4-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carbohydrazide (1) and indoline-2,3-dione (2) in boiling ethanol for 4 h under acidic conditions gave 1-(4-methoxyphenyl)-5-methyl-N’-(2-oxoindolin-3-ylidene)-1H-1,2,3-triazole-4-carbohydrazide (3) 88% yield. The structure 3 was ascertained by NMR spectroscopy single-crystal X-ray diffraction.

Two novel 3-amino-5-(4-choloro-2-phenoxyphenyl)-4H-1,2,4-triazole derivatives were prepared and their anticonvulsant activity was measured by evaluation of the ability of these compounds to protect mice against convulsion induced by lethal doses of pentylenetetrazole (PTZ). Diazepam (Sigma) was considered as a positive control drug with anticonvulsant effect [ED50 = 1.2 (0.5-1.9) mg/Kg]. Amongs...

Cp*-Ir(III) complexes with additional chelating ligands are known active pre-catalysts for the oxygenation of C-H bonds. We present here eight examples of such complexes where the denticity of the chelating ligands has been varied from the well-known 2,2'-bpy through pyridyl-triazole, bi-triazole to ligands containing pyridyl-triazolylidene, triazolyl-triazolylidene and bi-triazolylidenes. Addi...

BACKGROUND Benzimidazoles and triazoles are useful structures for research and development of new pharmaceutical molecules and have received much attention in the last decade because of their highly potent medicinal activities. FINDINGS A simple and efficient synthesis of triazole was carried out by treatment of 2-(4-azidophenyl)-1H-benzo[d]imidazole (6) with different types of terminal alkyn...
