Synthesis, characterization and spectral studies of new 4(Substituted phenyl hydrazono)-NI-(R)-amino malonyl-3-methyl-2-Pyrazolin-5-one and 3-methyl-4(Substitutedphenyl hydrazono)-Isoxazolone

ABSTRACT:

Synthesis of some new substituted 2-pyrazolin-5-one were synthesized by the condensation of 3-chloro-4-methoxy ethyl aceto hydrazone (1a) and different substituted phenyl malonamic acid hydraz ides(2a-2l) by using glacial acetic acid as a medium, substituted isoxazolone were synthesized by 3-chloro-4-methoxy ethyl aceto hydrazone(1a) and hydroxylamine hydrochloride with sodium acetate. The structures of synthesized compounds have been characterized by their physical properties and spectral analysis like IR.
