A unique 3D Cu(II) complex based on a molybdate oxide cluster and 5-triazole isophthalic acid was synthesized under hydrothermal condition: {Cu(2)(HL)(2)[Mo(4)O(13)]}·2H(2)O (H(2)L = 5-triazole isophthalic acid) (1). Compound 1 shows a spin canting magnetization behavior, and a definite hysteresis loop with a large coercive field of 6.85 kOe.

We report the synthesis and photospectroscopic characterisation of intrinsically fluorescent triazole-appended cytidines. Fluorescence was found to be highly dependent on solvent conditions. X-Ray crystallographic data show the proton of the exocyclic amine of the nucleobase and the triazole N(3) engaged in a H-bond.

The reaction of equimolar equivalents 1-(4-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carbohydrazide (1) and 2-acetylbenzofuran (2) in anhydrous ethanol containing a catalytic amount concentrated hydrochloric acid under reflux for 2 h gave (E)-N’-(1-(benzofuran-2-yl)ethylidene)-1-(4-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carbohydrazide (3) 86% yield. structure the title heterocycle 3 was ...

The title compound, C(11)H(13)N(5), is a Schiff base synthesized by the reaction of 4-amino-4H-1,2,4-triazole and 4-(dimethyl-amino)-benzaldehyde. The dihedral angle between the benzene and triazole rings is 43.09 (11)°. The crystal structure displays weak C-H⋯N inter-actions.

β-Hairpin peptides were conformationally stabilized through a 1,4 disubstituted 1,2,3-triazole interstrand linkage. A NMR conformational analysis revealed that the β-hairpin content depends on the number and position of substituent methylene units of the 1,2,3-triazole ring. These results will allow the design of metabolically stable peptidomimetic analogs of bioactive β-hairpin peptides.

A series of 1-alkyl-4-aryl-1,2,3-triazoles (1-methyl-4-phenyl-1,2,3-triazole (1a); 1-propyl-4-phenyl-1,2,3-triazole (1b); 1-benzyl-4-phenyl-1,2,3-triazole (1c); 1-propyl-4-p-tolyl-1,2,3-triazole (1d)) have been prepared through a one-pot procedure involving in situ generation of the alkyl azide from a halide precursor followed by copper catalysed alkyne/azide cycloaddition (CuAAC) with the appr...

A bioorthogonal 'catch and photorelease' strategy, which combines alkyne-azide cycloaddition between p-hydroxyphenacyl azide and alkyne derivatives to form a 1,2,3-triazole adduct and subsequent photochemical release of the triazole moiety via a photo-Favorskii rearrangement, is introduced. The first step can also involve photorelease of a strained alkyne and its Cu-free click reaction with azide.

A novel SBA-15 supported catalyst PdL(n)@SBA-15 containing a 2-pyridyl-1,2,3-triazole ligand framework was prepared via a "click" route, in which the click-triazole acted as both a stable linker and a good chelator. The catalyst was characterized and applied for the aerobic oxidation of alcohols, and the product was obtained in up to 98% yield.

This paper reports on the synthesis and characterization of two Schiff bases bearing 1,2,4-triazolic moieties, namely 4H-4-(2-hydroxy-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole and 4H-4-(4-nitro-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole using thin layer chromatography, melting interval, elemental analysis, spectroscopy and thermal stability studies.

Allene triazole derivatives were successfully synthesized for the first time through iron catalyzed regioselective triazole addition to tertiary propargyl alcohols. The reaction proceeds under mild conditions, giving the desired allene-triazoles in good to excellent yields (up to 96%). The resulting allene-triazoles were confirmed by X-ray crystallography and indicated improved stability.
