Synthesis, Characterization and Microbial Activity of 5-[1-(1,3-Benzothiazol-2-Ylsulfanyl)Alkyl]-1,3,4-Thiadiazole-2-(3h)-Thione
A number of benzothiazole-2-ylsulfanyl derivatives 2(1,3-Benzothiazol-2-ylsulfanyl)alkanoylhydrazide (IA – IG) and 5-[1-(1,3-Benzothiazol-2-ylsulfanyl)alkyl]-1,3,4-thiadiazole-2(3H) thione (IIA-IIG) have been synthesised from (1,3Benzothiazol-2-ylsulfanyl)acetic acid. These compounds were synthesied and characterized from their F.T.I.R, and H-NMR spectral studies. The compound (IIA to IIG) were...
متن کامل5-Ethoxy-1,3,4-thiadiazole-2(3H)-thione
In the title compound, C(4)H(6)N(2)OS(2), the dihedral angle between the five-membered heterocyclic ring and the plane of the eth-oxy group is 4.9 (2)°. The 1,3,4-thiadiazole-2-thione unit is planar, with an r.m.s. deviation of 0.011 Å from the corresponding squares plane defined by the seven constituent atoms. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into inversion dim...

متن کامل2-Methylsulfanyl-1,2,4-triazolo[1,5-a]quinazoline-5(4H)-thione
In the title compound, C10H8N4S2, comprising fused six-, six- and five-membered rings, the mol-ecule is close to being planar (r.m.s. deviation of the non-H atoms = 0.041 Å). The S-bound methyl group is folded away from the single N atom of the triazole ring and the NH group of the six-membered ring, allowing for the formation of centrosymmetric eight-membered {⋯HNCN}2 synthons in the crystal. ...
متن کامل5 - Amino - 3 - methyl - 1 , 2 , 4 - thiadiazole
An improved procedure for isolation of 5-amino-3-methyl-1,2,4-thiadiazole in pure form on a multi-gram scale without chromatography is reported. Its 1H and 13C-NMR and IR data are presented and previously published erroneous data corrected. The molecular structure is confirmed by X-ray diffraction which shows layers consisting of an elaborate two-dimensional hydrogen bonded network of molecules.
