Abstract
This search included synthesis of some heterocyclic compounds devired from 1,3,4-
thiadiazol ring ,such as thaiazolidin -4-one substituents Azetidine -3- one and Azo dyes.
These compounds were aprepard from Shiff bases loaded on thiazdiazol ring, These bases
have been treated with Aniline substituents in presence of pyrididine as a catalyst to give
azo dyes , thioglycolic acid to produce thiazolidine -4- one in presence of ZnCl2 as catalyst
and finally with chloroacetylchloride to produce Azetidine-3-one in presence of
tryethylamine as a catalyst. The prepared compounds were identifie by physical properties
and IR,H1-NMR Spectroscopy.
