Synthesis and Evaluation of Antioxidant Activities of 1,3-Diaryl-1H-pyrrazol4-carbaldehydes 

Abstract

A new series of 1,3-Diaryl-1H-pyrrazol-4-carbaldehyde has been synthesized from hydrzone of aromatic ketone and phenylhydrazine in presence of Vilsmear Hack reagent. The structures of synthesized compounds has been confirmed by elemental analysisFT-IR, 1H NMR, 13C NMR and mass spectral data. These synthesized compounds observed to show antioxidant activities by usingDPPH method using ascorbic acid as standard.Keywords: 1,3-Diaryl-1H-pyrrazol-4-carbaldehyde, Hydrzone, Vilsmear Hack reagent, Antioxidant activity
