Platinum arylthiolate complexes in different oxidation states

文摘
Several enzymes, which contain partly sulfur-coordinated nickel as the active site catalyse different redox reactions in biological systems. These reactions usually involve a change of the oxidation state of the metal. The heavier homologues of nickel, palladium and platinum and their compounds are well established as catalysts in industrial and general chemistry. Nevertheless, these metals usually do not show any catalytic or redox activity when they are mainly coordinated by sulfur ligands. Hitherto platinum thiolate complexes with the metal in the formal oxidation state +3 has not been described.
