Synthesis and Characterisation of Certain Medicinally Important Novel Pyrazolin-5- ones

N- Benzene sulfonyl -3-methyl-4- substistuted-arylhydrazono -pyrazolin-5-ones have been synthesized by the reaction between diazonium acetoacetic ester and benzene sulfonyl hydrazide. Pyrazolin-5-ones so obtained were characterized by elemental analysis, IR, 1H NMR and mass spectra.

Keywords:

Pyrazolin-5-ones characterization, elemental analysis, IR, 1H NMR, Mass spectral analysis,
