Regioselective synthesis of 1-(2,6-dichloro-4-trifluoromethylphenyl)- 4-alkyl-1H-[1,2,3]-triazoles.
A new and efficient method for the synthesis of 1-(2,6-dichloro-4-trifluoromethylphenyl)-4-alkyl-1H-[1,2,3]-triazoles by the room temperature 1,3-dipolar cycloaddition of (2-azido-1,3-dichloro-5-trifluoromethyl)benzene with terminal alkynes in the presence of Cu (I) salt as catalyst is reported. All the reactions gave 1,4-disubstituted products with high regioselectivity, as no 1,5-disubstitute...
متن کاملSynthesis of novel 1-[(2,6-dichloro-4-trifluoromethyl)phenyl]-3-aryl-1H-pyrazole-4-carbaldehydes.
A series of novel 1-[(2,6-dichloro-4-trifluoromethyl)phenyl]-3-aryl-¹H-pyrazole-4-carbaldehydes were synthesized using the Vilsmeier-Haack reagent. The structures of all the title compounds have been confirmed by elemental analysis, ¹H-NMR and ¹³C-NMR and in addition, the structure of intermediate 5b was investigated by X-ray crystallography.

The title compound, C(18)H(7)BrCl(2)F(3)N(5)O(2), is an L-shaped tricyclic imine. The pyrazole ring is essentially coplanar with the nitro-substituted benzene ring [dihedral angle = 3.6 (2)°] and approximately perpendicular to the trifluoro-methyl-substituted ring [dihedral angle = 88.5 (2)°].
متن کاملSynthesis and Biological Activity of Certain Mannich Bases Derivatives from 1, 2, 4-Triazoles
Substituted 1, 2, 4- Triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. These triazoles were used for preparation of different derivatives by two different schemes. In the first scheme the Mannich bases were prepared from 5- marcapto-s triazole Quinazolines. The 5-Marcato-s-Tr...
