Azotation and Coupling Reaction of Amino Oxadiazole Ligands with (Characterization, Chromatography, Solubility) Study
Abstract
This paper involved reaction between two moles of semicarbazide with mole of diethyl malonate which refluxed for ( 17 hrs ) in absolute ethanol then added ( 4 ml ) of H2SO4 to produce amino oxadiazole , the resulting compound used in azotation then coupling reaction with various coupling derivatives of phenol ( p-hydroxy benzaldehyde , p-hydroxy benzoic acid , p-hydroxy nitrobenzene , p- hydroxyl toluene , p- hydroxyl phenol )to produce novel oxadiazole derivatives as a ligands .The above ligands were investigated through their spectral methods (UV- Vis , FTIR ,1HNMR , Mass ) , Chromatography technique and studying of solubility in series solvents.
Keywords: Soluble, Series, Hydroxyl.
