Abstract: Aseries of new s-triazolo[3,4-b]-1,3,4-thiadiazole, 1,2,4-triazole and 1,3,4-oxadiazole derivatives were synthesized from 6-nitrobenzimidazol 1-acetic acid hydrazide and 4-amino-5-mercapto-3-(6-nitrobenzimidazol 1-methylene)-1,2,4-triazole, respectively. The structures of the compounds synthesized were confirmed by elemental analyses, ¹H NMR, IRand MS. Their spectral properties were also discussed.

Key words: 6-Nitrobenzimidazole, s-Triazolo[3,4-b]-1,3,4-thiadiazole, 1,2,4-Triazole, 1,3,4-Oxadiazole, Synthesis
