In the title thione, C(26)H(36)N(6)OS, the 1,2,4-triazole ring is planar (r.m.s. deviation = 0.020 Å) and the benzene ring is twisted out of this plane [dihedral angle = 62.35 (12)°]. Supra-molecular zigzag chains feature in the crystal packing. These are sustained by O-H⋯N(piperazine) hydrogen bonds, and are connected into the three-dimensional crystal structure by C-H⋯S and C-H⋯O inter-action...

In the present investigation, new hydrazinecarbothioamides 4-6 were synthesized by reaction of 4-(4-X-phenylsulfonyl)benzoic acids hydrazides (X=H, Cl, Br) 1-3 with 2,4-difluorophenyl isothiocyanate and further these were treated with sodium hydroxide to obtain 1,2,4-triazole-3-thione derivatives 7-9. The reaction of 7-9 with α-halogenated ketones, in basic media, afforded new S-alkylated deriv...

ABSTRACT. A series of nine new 6-aryl-7-alkyl/aryl-[1,2,4]triazolo[4,3-a][1,3,5]triazine-5(6H)-thiones (2a-i) were synthesized by a reaction N-triazol-3-yl imidates (1) with three different isothiocyanate derivatives (RNCS) in refluxing toluene. The structures the final heterocyclic compounds confirmed 1H-NMR, 13C-NMR, FT-IR, elemental analysis, and mass spectral analysis. target vitro screened...

BACKGROUND 1,2,4-Triazole3-thiones are good scaffolds for preparation of new lead compounds. Their derivatives attracted the attention of chemists due to their wide spectrum of biological activities. Alkylsulfanyl-1,2,4-triazoles have three nucleophilic sites (nitrogens) ready for reaction with electrophiles. Herein, new regioselective isomers were synthesized by the reaction of benzylsulfanyl-...

The title compound, C18H20ClN3S, is a functionalized triazoline-3-thione derivative. The benzene ring is almost perpendic-ular to the planar 1,2,4-triazole ring [maximum deviation = 0.007 (1) Å] with a dihedral angle of 89.61 (5)° between them and there is an adamantane substituent at the 3-position of the triazole-thione ring. In the crystal, N-H⋯S hydrogen-bonding inter-actions link the mol-e...
