The coordination chemistry ofPhenylcyanamides and its substituted derivatives began with a study by Hollebone in 1971 but remained largely unexplored until the late 1980s.This is surprising as the coordination chemistry of Phenylcyanamides should-be as rich as that of other Pseudo halides such as azide and thiocyanate.Indeed, the attachment of a phenyl ring to the cyanamide group adds an extra dimension not present in azide or thiocyanate ligands.An extensive ? conjugation between the cyanamide group and the phenyl ring provides an energetically favorable means by which a metal ion can couple into a conjugation organic ? system. Phenylcyanamides and its derivatives can be readily prepared in high yields from the corresponding anilines by desulfurization of the thiourea derivatives. In the project, first the thiourea synthetic route to 4-nito Phenylcyanamide, Iron(II) complex with the ligand of 4-nito Phenylcyanamide and ligand of 1,10 phenantroline and Iron(III) complex with these two ligands were synthesized and characterized by FT-IR,UV-Vis, 1 H-NMR spectroscopy techniques. Nitrile hydratase, catalyzing the hydration reaction of nitrile to amides, is an important enzyme which has been used in the industrial production. Aliphatic nitriles are generally metabolized in twostages. In the recent years, metal-mediatedand metal-catalyzed hydrolysis of nitrile ligands haveexperienced a rapid growth in two main directions, namely (i) the metal-mediatedhydrolysis giving amides which remain ligated and special methods arerequired to perform their liberation and (ii) the homogeneouscatalytichydrolysis when the amides formed areexpelled from the coordination sphere of the metal ionswith regeneration of active metal species. Interesting phenomenon in this project is Hydrolysis of Phenylcyanamide to phenyl urea derivatives and studying effects of this Complex as a Iron supply ofTomato in Hydroponic.
