Synthesis and Characterization of Novel Azole Heterocycles Based on 2,5-Disubstituted Thiadiazole

Authors: NADIA A. SALIH

Abstract: Starting from 2-amino-5-mercapto-1,3,4-thiadiazole (1), a variety of new 1,2,4-triazino[5,4-b][1,3,4] thiadiazole (3), pyrazole (4), [1,2,4]triazolo[3,4-b] [1,3,4]thiadiazole (5), phthalazine-3,6-dione (6), azo derivatives (9), pyrimidine -2,4,6-trione (11), Schiff base (12) and pyrrolidine (13) derivatives have been synthesized. All proposed structures were supported by FT-IR, ^1H-NMR, ^{13}C-NMR elemental analysis, and MS spectroscopic data.

Keywords: 1,3,4-thidiazoles, fused heterocyclic ring, Schiff bases
