5-Furan-2yl[1,3,4]oxadiazole-2-thiol, 5-furan-2yl-4H [1,2,4] triazole-3-thiol and their thiol-thione tautomerism.
5-Furan-2-yl[1,3,4]oxadiazole-2-thiol (Ia) and 5-furan-2-yl-4H-[1,2,4]-triazole-3-thiol (Ib) were synthesized from furan-2-carboxylic acid hydrazide. Mannich bases and methyl derivatives were then prepared. The structures of the synthesized compounds were confirmed by elemental analyses, IR and (1)H-NMR spectra. Their thiol-thione tautomeric equilibrium is described.
متن کاملSynthesis and Antioxidant Activity of 2-Amino-5-methylthiazol Derivatives Containing 1,3,4-Oxadiazole-2-thiol Moiety
A series of new 5-(2-amino-5-methylthiazol-4-yl)-1,3,4-oxadiazole-2-thiol derivatives 6(a-j) were designed and synthesized with various substituted aldehydes. The chemical structures were confirmed by elemental analyses, FT-IR, (1)H NMR, and mass spectral studies. The antioxidant activity of the synthesized compounds was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl, nitric oxide,...
متن کاملGreen 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 کامل2-(4-tert-Butylphenyl)-5-p-tolyl-1,3,4-oxadiazole
In the title compound, C(19)H(20)N(2)O, the dihedral angles between the 1,3,4-oxadiazole ring and the pendant 4-tert-butyl-phenyl and 4-methyl-phenyl rings are 12.53 (17) and 2.14 (17)°, respectively. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains.
متن کامل2-(Adamantan-1-yl)-5-(4-nitrophenyl)-1,3,4-oxadiazole
The title mol-ecule, C(18)H(19)N(3)O(3), lies on a mirror plane that bis-ects the adamantyl group. In the crystal, C-H⋯O and C-H⋯N inter-actions lead to supra-molecular chains along [100]. These assemble into layers in the ab plane via π-π inter-actions [centroid-centroid distance = 3.6548 (7) Å] between the oxadiazole and benzene rings.
