Studies On The Synthesis Of 3, 6-Dichloro-Pyridine-2-Carboxylic Acid Acyl Hydrazones And 2, 5-Disubstituted-1, 3, 4-Oxadiazolines

The interest in the study of hydrazones has been growing, due to their strong coordination ability, diverse coordination forms, broad spectrum of the biological and pharmaceutical activity and well characters in nonlinear optics. Oxadiazolines and its derivatives have very important bioactivity like anti-inflamemation, antibacterial, adjust plants in growing, killing pest, and other properties. Also it plays important role in medicine industry and agriculture.The dissertation is consisted of the following:(1) Sixteen new 3,6-dichloro-pyridine-2-carboxylic acid acyl hydrazones were synthesized and characterized by elemental analyses, ¹H NMR and IR spectra.(2) Seven new 3,6-dichloro-pyridine-2-carboxylic acid oxadiazolines, were synthesized and characterized by elemental analyses, ¹H NMR, ¹²C NMR and IR spectra.(3)The structure of (E)-N'-(4-Chlorobenzylidene)-3,6-dichloropicolino-...
