Synthesis and applications of oxomolybdenum compounds

Abstract

Molybdenum enzymes, which carry a pterine-based molybdenum cofactor in their center, are enzymes, which catalyze plenty of reactions in the human body and play therefore a very important role in its metabolism. Pterine-based molybdenum cofactor (Moco) Redox reactions and oxygen transfer reactions, which are omnipresent in the human's metabolism, are performed with the aid of these enzymes. The absence of enzymes of this kind can cause various health problems, which can lead to several disorders or even death in the early childhood. Since research is very important in this area, model systems of Moco are formed, which hold the possibility to examine the reactivity, the redox potential and also the geometry of different pterine-based molybdenum cofactors. In model systems of Moco bidentate sulfur donor ligands should be coordinated to the molybdenum metal center. bidentate sulfur donor ligands In this thesis the synthesis of a respective ligand was performed and the coordination to molybdenum succeeded, yielding the compound shown in the figure below. Synthesized model compound Parts of this thesis were performed at the Institute of Technology in Izmir (IZTECH) in course of my ERASMUS-year in Turkey.
