Metal complexes were prepared by the reaction of thiosemicarbazone with CuCl2, NiCl2, CoCl2, Cu(OAc)2, Ni(OAc)2, and Co(OAc)2. The thiosemicarbazone coordinates to metal through the thionic sulfur and the azomethine nitrogen. The thiosemicarbazone was obtained by the thiosemicarbazide with 3-acetyl-2,5-dimethylthiophene. The identities of these compounds were elucidated by IR, (1)H, (13)C-NMR, ...

We have been interested for some time in thiosemicarbazide derivatives of periodate-oxidized polysaccharides many of which show considerable activity against Sarcoma 180 (S-180) in the mouse (2). The antitumor activity and toxicity of these deriva tives are completely reversed if pyridoxine (B6) is administered at the same time. We were led to investigate glyoxal and methylglyoxal bisthiosemica...

CuInS2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  In  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. The effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  The nanostructures  were  characterized  by  means ...

An environmentally benign and clean synthesis of aryl-hydrazones by reacting variety of carbonyl compounds with thiosemicarbazide, semicarbazide, aminoguanidine, and phenyl hydrazine has been achieved using aqueous extract of Acacia concinna pods as a natural surfactant type catalyst. We found that the aqueous extract of Acacia concinna pods could be effectively used for the synthesis of aryl-h...

5- Amino -3- [4- O- hydroxypheny Ithiosemi carbazido ] -1,2,4-thiadiazole compound has been prepared by the reaction of ( 3-mercapto -5- ami,2,4- thiadiazole) with O-hydroxyphenyl thiosemicarbazide) in mole ratios (1:1) .The ligand characterized and its structure was elucidated depending upon spectral data IR U.V-Vis spectra . Lanthanum complex formula [La( C9H10N6S2O)2Cl2]Cl through lanthanum ...

Thiosemicarbazides are potent intermediates for the synthesis of pharmaceutical and bioactive materials and thus, they are used extensively in the field of medicinal chemistry. The imine bond (-N=CH-) in these compounds are useful in organic synthesis, in particular for the preparation of heterocycles and non-natural β-aminoacids.In this paper the synthesis of some new thiosemicarbazide derivat...
