A series of new 1,2/1,3-bis[o-(N-methylidenamino-3-aryl-5-phenyl-4H-1,2,4-triazole-4-yl)phenoxy]ethane/propane derivatives 4 were prepared in good yields by treatment of 4-amino-3-aryl-5-phenyl-4H-1,2,4-triazoles 2 with certain bis-aldehydes 1.Compounds 4 were reduced with NaBH(4) to afford the corresponding 1,2/1,3-bis[o-(N-methylamino-3-aryl-5-phenyl-4H-1,2,4-triazole-4-yl)phenoxy]ethane/prop...

In the title compound, C(16)H(17)N(3)O(2)S·H(2)O, the triazole ring makes a dihedral angle of 34.63 (6)° with the benzene ring. The thio-phene ring is disordered over two orientations [occupancy ratio = 0.634 (4):0.366 (4)] which make dihedral angles of 54.61 (16) and 54.57 (31)° with the triazole ring. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds stabilize the crystal structure.

In this manuscript, a new series of 1,2,4-triazole-3-ones containing imin function was synthesized from 5-(4-bromobenzyl)-4-amino-2H-1,2,4-triazol-3(4H)-one and aromatic aldehyde by using microwave irradiation technique via schiff base reaction. Firstly, ethyl imido-p-bromophenylacetate hydrochloride (2) according to the pinner method in literature. Then, compound 2 reacted with carbazate p-bro...

The Objective of this study is created a novel derivative the naproxen with heterocyclic (1,2 and 4 triazole) ring that reacted benzoyl chloride derivatives, as well preliminary antibacterial activity testing formed products. derivatives are synthesized by esterifying hydrazine hydrate, then reacting hydrated carbon disulfide, finally reaction (in final step) triazole including amino group via ...

In this study appropriate hydrazide compounds, furan-2-carboxylic acid hydrazide (1) and phenylacetic acid hydrazide (2) were converted into 1,4-substituted thiosemicarbazides 4a-e and 5a-e and 4-amino-5-(furan-2-yl or benzyl)-4H-1,2,4-triazole-3-thiols 7 and 10. The 1,4-substituted thiosemicarbazides were then converted into 5-(furan-2-yl or benzyl)-4-(aryl)-4H-1,2,4-triazole-3-thiols 8a-e and...

In the title mol-ecule, C(31)H(26)N(4)O(2)S, the phenyl ring attached to the 1,2,4-triazole ring forms dihedral angles of 65.4 (2), 63.4 (2) and 62.2 (2)° with the other three rings. The 1,2,4-triazole ring makes dihedral angles of 78.0 (2), 87.9 (2), 24.9 (2) and 62.8 (2)° with three phenyl rings and the methoxyphenyl ring.

The asymmetric unit of the title compound, C(9)H(8)N(4)O(3), contains two independent mol-ecules. The dihedral angles formed by the triazole and benzene rings in the two independent mol-ecules are 83.3 (3) and 86.9 (4)°. The mol-ecular packing involves weak C-H⋯N and C-H⋯O inter-actions, and π-π stacking inter-actions [centroid-to-centroid distance 3.745 (1) Å] between the aromatic rings of pai...

In the title compound, C(4)H(8)N(4), inter-molecular N-H⋯N hydrogen bonds involving the amino groups and triazole N atoms form a two-dimensional sheet.
