A series of novel pyridine, sulfonamide, coumarin, thiophene, α,β-unsaturated carbonyl compounds, and pyrazole derivatives were synthesized from hydrazide-hydrazone derivatives with different reagents (substituted benzaldehydes, hydrazine hydrate, malononitrile, 2-hydroxy-1-naphthaldehyde, tetralone, cyclopentanone, and ethyl cyanoacetate). Hydrazide-hydrazone derivatives were prepared by reactions 2-cyanoacetohydrazide with 2-acetylpyridine or 4-acetyl-N-(p-tolyl)benzenesulfonamide. On the basis of their spectral information, the structures of the newly synthesized chemical derivatives were determined.
