| Abstract: | 5-Furan-2-yl1,3,4]oxadiazole-2-thiol (Ia) and 5-furan-2-yl-4H-1,2,4]-triazole-3-thiol (Ib) were synthesized from furan-2-carboxylic acid hydrazide. Mannich bases and methyl derivatives were then prepared. The structures of the synthesized compounds were confirmed by elemental analyses, IR and (1)H-NMR spectra. Their thiol-thione tautomeric equilibrium is described. |
