This work discuss methods of preparation a series of organic is at in ligands via imination process, diazotaion reaction , cyclization reaction in types of conditions to synthesis many ligands from is at ine derivatives like ( is at in-thiadiazole , is at in- triazole, is at in- azo , is at ine –anil). All present organicis at ine ligands were characterized by spectral identification with types of techniques (Uv.Vis , FT.IR ,H.NMR, C.NMR)– spectrophotometric.
