Synthesis and characterization of novel azole heterocycles based on 2,5-disubstituted thiadiazole
Starting from 2-amino-5-mercapto-1,3,4-thiadiazole(1), a variety of new1,2,4-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, H-1-NMR, C-13-NMR elemental analysis, and MS spectroscopic data.
