Synthesis and Characterization New Schiff-base Compounds from Thiadiazole Derivative

Abstract

In this paper Synthesis of new different Schiff-base heterocyclic compounds from azo dye [S1] by the reaction between p-aminobenzoic acid and resorcinol,also [S1] was cyclized by reaction with thiosemicarbazide to form 1,3,4-thiadiazole amine [S2],which reacted with (9-anthraldehyde,terephthaldehyde, N,N-dimethyl amino benzaldehdye,3,5-dichloro salicyaldehyde,3-hydroxybenzaldehdye,2-hydroxy-5-nitro benzal dehyde) in presence of acetic acid to give new Schiff-base compounds, after that these compounds were characterized by the following techniques: FT-IR, 1HNMR,13C-NMR and elemental analysis CHNS.
