Abstract

The present research has systematic approach to synthesized a series of 1- phenyl-4-yl-methanone-3,5-disubstituted Pyrazoles ( 3a-d) and 1- pyridine-4-yl-methanone-3,5-disubstituted pyrazoles ( 5a-c ) derivatives by the action of substituted 1,3-disubstituted propane-1,3-diones with phenyl hydrazide and isoniazide respectively. The compounds were synthesized by green chemistry technique. Structures of all the synthesized compounds were confirmed by their IR, 1H-NMR.
