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.
