Abstract

This work includes preparation of 5-Amino-1,3,4-thiadiazole-2-thiol from thiosemicarbazide with Carbon disulfide (CS2) and KOH as catalyst. Also reaction of 5-Amino-1,3,4-thiadiazole-2-thiol with different aromatic aldehydes by using glacial acetic acid as catalyst to synthesis of some new Schiff bases derivatives that coupled with thioglycolic acid to synthesis five- member ring heterocyclic compounds derivatives. All synthetic compounds were definited by their melting point, FT-IR spectra and 1H-NMR spectra for some of them.Keywords: 5- Amino-1, 3, 4-thiadiazole-2-thiol, Thiosemicarbazide, Schiff bases, heterocyclic compounds, thiadiazole.

Abstract

This work includes synthesis of hydrazide from 5-Amino-1, 3, 4-thiadiazole-2-thiol. Also reaction of hydrazide with different aromatic aldehydes by using glacial acetic acid as catalyst to synthesis of some new Schiff bases derivatives that coupled with thioglycolic acid to synthesis five- member ring heterocyclic compounds derivatives containing thiazolidinone ring. All synthetic compounds were definite by their melting point, FT-IR spectra and 1H-NMR spectra for some of them.Keywords: 5-Amino-1, 3, 4-thiadiazole-2-thiol, thiazolidinone, Schiff bases, Heterocyclic compounds, Thiadiazole.
