Abstract

In this work, thiadiazole derivatives were prepared by taking advantage of active sites in (2-amino-5-mercapto1, 3, 4-thiadiazole) as base. The main hetrocyclic compounds (1, 3, 4-thiadiazole, oxazole) etc. 2-amino-5mercapto-1, 3, 4-thiadiazole compound [1] was prepared by cyclic closure of thiosemicarbazide compound with anhydrous sodium carbonate and carbon disulfide. Oxidation of [1] via hydrogen peroxide, to have [2] which was treat with chloro acetyl chloride to get [3]. Preparation of oxazole ring [4] obtained from reacting of [3] with urea. Schiff bases [5–7] prepared by reacting [3] with different benzyl aldehyde. And Preparation of derivative [8–11], from reaction [3] with of hydrazine derivatives. Full characterization of the synthesized compounds was done by using of spectroscopic analysis such as FT-IR, 1H-NMR and C.H.N.S,
