Green synthesis and evaluation of 5-(4-aminophenyl)-4-aryl-4H-1, 2, 4-triazole-3-thiol derivatives
The green synthesis of 5-(4-aminophenyl)-4-aryl-4H-1,2,4-triazole-3-thiol was achieved in four steps, In first step, 4-amino benzoic acid refluxed in ethanol along with catalyst Conc. Sulphuric acid to produce ethyl-4-amino benzoate I. Further compound I refluxed with hydrazine hydrate in ethanol to produce 4-amino benzohydrazide II. Compound II refluxed in ethanolic potassium hydroxide with ca...

متن کاملSynthesis and Antibacterial Activity of Some New Functionalized Derivatives of 4-amino-5-benzyl-4H-[1,2,4]-triazole-3-thiol
The use of 4-amino-5-benzyl-4H-[1,2,4]triazole-3-thiol (1) as a precursor to synthesize some new biologically active heterocycles has been found to be effective. Condensation of 1 with appropriate aldehydes gave the new Schiff bases 2a, b, which either by cyclization with thioglycolic acid gave 3a, b, or by Mannich reaction using morpholine gave 4a, b. Reaction of 1 with different halogen compo...
متن کامل4-Amino-3-(4-pyridyl)-1,2,4-triazole-5(4H)-thione
In the title mol-ecule, C(7)H(7)N(5)S, the pyridyl and triazole rings form a dihedral angle of 20.07 (6)°. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains extended in the direction [10]. Further stability is provided by π⋯π stacking inter-actions, indicated by short distances between the centroids of triazole rings [3.480 (5) Å] and pyridyl rings [3.574 (5) Å] of neighbouri...
متن کامل4-Amino-3-phenyl-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(8)H(8)N(4)S, the planar triazole ring forms a dihedral angle of 13.7 (2)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H⋯S hydrogen-bond inter-actions, linking the mol-ecules into chains along the a axis.
