Synthesis, characterization of some new 1 -phenyl (3-chloro- 4-methoxy, 2-methoxy-5-methyl)- 4(substituted) phenyl benzene-azo acetyl acetone-3,5-di methyl pyrazoles

摘要

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 (R')-malon phenyl anilic acid hydrazide (3a-3i.Sj.Sj,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.
