Four heterocyclic ligands [1,3-diarylpyrazole-4-carbaldehyde semicarbazones] and their metal complexes with d-block transition elements (Cu2+, Ni2+, CO2+, Pb2+, Zn 2+ and Fe2+) have been synthesized and characterized through elemental analysis and spectroscopic techniques viz., FTIR, 1H NMR and mass spectra.

Ligational behavior of thiosemicarbazones and semicarbazones derived from 1-phenyl-3-arylpyrazole-4-carboxaldehydes towards triphenylchlorosilane has been investigated by elemental analysis, molar conductivity measurements, and IR, 1H, 13C, and 29Si NMR spectroscopic studies. The ligands and their organosilicon complexes have also been evaluated for in vitro antimicrobial activity against some pathogenic bacteria and fungi.

One-pot synthesis of some new semicarbazone, thiosemicarbazone, and hydrazone derivatives of 1-phenyl-3-arylpyrazole-4-carboxaldehyde from acetophenone phenylhydrazones using Vilsmeier-Haack reagent

Semicarbazone derivatives 3 of 1,3-diphenylpyrazole-4-carboxaldehyde have been synthesized in high yields through a one-pot procedure involving acetophenone phenylhydrazones 1 subjected to Vilsmeier double formylation and workup under new conditions (i.e., treatment with semicarbazide followed by sodium bicarbonate). This method is even suitable for preparing other derivatives (i.e., thiosemicarbazones 4 and hydrazones 5) in high yields. Copyright Taylor & Francis Group, LLC.
