A highly efficient method for the synthesis of thiadiazole derivatives via intramolecular oxidative coupling of thiosemicarbazide, using the in situ generated hypervalent iodine(III) reagents is developed. The protocol can be carried out smoothly and provides a variety of thiadiazole derivatives in moderate to excellent yields. Graphical Abstract: A highly efficient method for the synthesis of thiadiazole derivatives via PhI-catalyzed intramolecular oxidative coupling of thiosemicarbazide has been developed.

Paragraph 0045, (2017/06/02)
The invention discloses a phenyl-2-acetal N-phenyl thiosemicarbazide ruthenium aryl complex as well as a preparation method and application thereof. The complex has a structural formula (III) in the specification. The chemical name of the complex is trichloromonomethyl isopropylbenzene ruthenium (II) monochloro-phenyl-2-acetal N-phenyl thiosemicarbazide-methyl isopropylbenzene ruthenium (II). The complex shows good inhibitory activities towards gastric cancer SGC7901 cell lines and liver cancer BEL-7404 cell lines, can be used for preparing medicines for treating cancers, and can be used after being prepared into the forms, such as injections, tablets, pills, capsules, suspending agents or emulsion. The preparation method of the phenyl-2-acetal N-phenyl thiosemicarbazide ruthenium aryl complex is simple, is accessible in raw materials and has the advantage of low cost.

experimental part, p. 616 - 623 (2010/07/18)
(Chemical Equation Presented) A simple and efficient procedure for the synthesis of 1,3,4-thiadiazoles has been achieved using thiourea as organocatalyst. In this study, the steric and electronic effects using structurally different derivatives of urea and thiourea in different solvents were evaluated. The best yields and the rate of the reactions were obtained using 30 mol % of thiourea as catalyst in acetonitrile at room temperature. The molecular structures of the products were established by 1H and 13C NMR spectral data.

The complexes of parachlorotribenzyltin (IV) chloride and parachlorodibenzyl tin (IV) dichloride with aniline N-thiohydrazide (L 1), and benzaldehyde aniline N-thiohydrazone (L2) have been synthesized. The complexes have been characterized by elemental analysis and spectral (UV-VIS, IR & NMR) studies. Ligand in the complexes acts as bidentate and coordination takes place through sulphur and terminal nitrogen. These are 1:1 metal ligand complexes. Various thermodynamic parameters have been calculated for the decomposition steps using TG-DTA curves. Activity of all the complexes Vs. Rhizoctonia bataticola fungal strain have been studied and the general order of activity have been deduced.

[N-(2-pyridyl)-N'-(4-(un) substituted] thioureas and (substitutedaryl)thiosemicarbazones were synthesised and evaluated for their antibacterial activity. All aryl thiosemicarbazones showed good activity against Aeromonas hydrophilia and Salmonella typhimuriurn. But none of the pyridyl thioureas showed any prominent activity against tested bacteria.
