The title compound, C(11)H(9)N(5)O(2)S, was synthesized from N-phthaloylglycine and thio-carbohydrazide by the fusion method. This is the first report of a triazole derivative of N-phthaloylglycine. The title compound exists in the thione form. The mol-ecule is non-planar, with a dihedral angle between the isoindoline ring system and the triazole ring system of 82.24 (5)°. The crystal structure...
The title compound, C(8)H(8)N(2)S, was prepared by the condensation of N-methyl-1,2-phenyl-enediamine and carbon disulfide. The crystal structure is stabilized by a C-H⋯π inter-action between a benzene H atom and the benzene ring of a neighbouring mol-ecule, and by inter-molecular N-H⋯S inter-actions.
The study investigated the corrosion-inhibitory properties of three synthetic triazole Mannich bases on C1018 carbon steel using various electrochemical techniques. inhibitors, namely 4-amino-2-[(4-methylpiperazin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (4MPT), 4-amino-2-[(piperidin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (PPT) and 4-ami...
The title compound, C(17)H(16)N(2)S(2), a dithio-carbazate derivative, adopts an EE configuration with respect to the C=C and C=N double bonds of the propenyl-idine group. The 3-phenyl-prop-2-enyl-idene and dithio-carbazate fragments lie essentially in the same plane, with a maximum deviation from that plane of 0.074 (2) Å, while the dihedral angle between the 3-phenyl-prop-2-enyl-idene and the...
A series of Schiff and Mannich bases derived from 4-amino-5-(3-fluoro-phenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione were synthesized. The alkylation of 4-phenyl-5-(3-fluorophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione with propargyl bromide afforded the corresponding thiopropargylated derivative which upon treatment with the appropriate secondary amines in the presence of CuCl2 furnished the ...
Electrochemical behavior of I-hydroxypyridine-2-thione and its vanadium complex is studied using polarographic techniques. Polarograms of ligand and that of the complex is shown with diffusion characteristics of the waves. Cyclic voltagram of thione is investigated which shows that a reversible oxidation reduction of one electron process is taking place. PKa of the thione is found to be in ...
The title compound, C(5)H(4)Br(2)S(4), consists of a statistically planar, 4-bromo-1,3-dithiole-2-thione unit [maximum deviation from the ring plane 0.001 (2) Å], with a bromo-ethyl-sulfanyl substituent in the 5-position. In the crystal structure, weak inter-molecular S⋯S [3.438 (15) and 3.522 (15) Å] and S⋯Br [3.422 (14) and 3.498 (14) Å] inter-actions generate a three-dimensional supra-molecu...
