Synthesis and Spectroscopic Characterization Study of Some Schiff Bases 1,3[N,N-Bis(5-Methyl-1,3,4-Triazole-2-Thione)] Benzene and 1,4[N,N-Bis(5-Methyl-1,3,4-Triazole-2-Thione)] Benzene

Some of triazole derivatives are synthesized by cyclization reaction of thiocarbohydrazide synthesized by reaction of carbon disulphide and aqueous hydrazine; the basic nucleus 3-methyl-4-amino-1,2,4-triazole-5-thione (L) is prepared by reaction of thiocarbohydrazide compound with glacial acetic acid under reflux condition. The compound (L) is subjected to addition reaction with different aldehydes to synthesize Schiff bases 1,3[N,N-Bis(5-methyl-1,3,4-triazole-2-thione)] benzene (L1) and 1,4[N,N-Bis(5-methyl-1,3,4-triazole-2-thione)] benzene (L2). The compounds (L1) and (L2) are confirmed by means of their melting point, FTIR, UV-visible, and 1H-NMR spectra

KEY WORDS: synthesis, Schiff bases, thiocarbohydrazide, triazole derivatives
