A series of Schiff base compounds were synthesized from N-arylpyrazole derivatives in ionic liquid and the structures were confirmed by IR, 1H NMR spectra and elemental analysis.

Synthesis and COX-2 inhibitory activities of 1,5-diaryl pyrazole derivatives;

We have synthesized a series of novel pyrazole derivatives ligands.

From pyrazole link\'s four different substitution position spotst,he including fluorine pyrazole derivative re-search development was discussed.

Twenty new 3-arylmethylidenehydrazinocarbonyl-5-(p-substituted phenyl)-pyrazole derivatives were designed and synthesized in good to excellent yields using 4-substituted acetophenone and diethyl ox-alate as the starting materials.

We also describe synthetic reactions of imidazole and pyrazole derivatives using D-fructose and pyrazole as precursors to prepare multidentate ligands containing {NS} d.
