SYNTHESIS AND SPECTRAL CHARACTERIZATION OF SOME SUBSTITUTED DERIVATIVES OF 4-CHLORO-PYRAZOLINES

The present investigation deals with the synthesis of some chloro-pyrazolines from substituted pyrazolines. The synthesized chloro pyrazolines were characterized by elemental analysis, IR and NMR spectral analysis; the result of spectral analysis reveals presence of hydroxyl, methoxy, methyl and chloro functional groups along with the presence of aromatic ring which was also evident in the 1 H-NMR spectra which suggest successful synthesis of desired compounds.
