this study was carried out to evaluate the antifungal efficacy of garlic essential oil (allium sativum l.) and two fungicides including metalaxyl- mancozeb and mancozeb against phytophthora melonis, p. drechsleri and p. capsici the causal agent of damping- off on pepper, melon and cucumber, in vitro and greenhouse conditions. fungal radial growth for each concentration of garlic oil on phytopht...

In the title compound, C(19)H(15)N(3), the benzyl group is almost perpendicular to the triazole ring [dihedral angle = 80.64 (8)°], while the napthyl group makes an angle of 30.27 (12)° with the plane of the triazole ring. This conformation is different from the 1-benzyl-4-phenyl-1H-1,2,3-triazole analogue, which has the benzyl ring system at an angle of 87.94° and the phenyl group at an angle ...

The title compound (systematic name: N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide), C16H22N4O3S, is a triazole herbicide. The dihedral angle between the planes of the triazole and benzene ring planes is 88.14 (10)°. In the crystal, C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions link adjacent mol-ecules, forming one-dimensional chains along the a axis.

Objectives . A key step in the synthesis of natural nucleoside analogs is formation a glycosidic bond between carbohydrate fragment and heterocyclic base. Glycosylation methods differ terms regio- stereoselectivity. promising method for highly specific new pharmacologically active compounds involves an enzymatic reaction catalyzed by genetically engineered phosphorylases. This study devoted to ...

The ligands 1-(cyclohexyl)-4-(2-pyridyl)-1,2,3-triazole (1), 1-(2,6-diisopropylphenyl)-4-(2-pyridyl)-1,2,3-triazole (2), 1-(4-butoxyphenyl)-4-(2-pyridyl)-1,2,3-triazole (3) and 1-(methyl)-4-(2-pyridyl)-1,2,3-triazole (4) were synthesized by the Cu(I) catalyzed "Click" reaction between 2-pyridylacetylene and the corresponding azides. The ligands were then reacted with NiBr(2)·3H(2)O to generate ...

Functional and condensed derivatives of 1,2,4-triazoles are mostly used as biologically active compounds, modern studies increasingly report their successful use surfactants, stabilizers for the formation nanoparticles, components hybrid perovskites, which promising materials opto-electronics.
 Synthesis new [1,3]thiazolo[3,2-b][1,2,4]triazol-7-ium salts containing a long-chain heptadecyl ...

During the synthesis of functionalized energetic triazole derivatives for biosensor detection devices 1 carboxymethyl 3 diazonio 5 nitrimino 1,2,4 triazole (2) was obtained by nitration of sodium 1 carboxymethyl 3,5 diamino 1,2,4 triazole (1). Zwitterionic (2) behaves like a diazonium cation which was proved from its reaction with sodium azide by the formation of 3 azido 5 nitrimino 1,2,4 triaz...
