ABSTRACT:

This review introduces the synthesis of some newly 1-phenyl (3-chloro-4-methoxy, 2-methoxy-5-methyl)- 4(substituted) phenyl benzeneazo acetyl acetone-3,5-dimethyl pyrazoles (4a-4l, 5a-5l) containing different selected functional groups have been synthesized by condensing (3-chloro-4-methoxy, 2-methoxy-5-methyl) phenyl benzeneazo acetyl acetone hydrazone (1a,2a) with (RI) -malon phenyl anilic acid hydrazide (3a-3i,3j,3j1,3k,3k1-3l) in alcoholic medium, presence of glacial acetic acid as a catalyst. The identity of newly synthesized compounds were confirmed on the basis of their spectral studies viz- IR, physical properties, elemental analysis.
