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...
