Biokatalytisch relevante rautenförmige Bis(μ-oxo)dimetall-Kerne in Kupfer- und Eisenkomplexen

Abstract: Obwohl es in der Chemie des hochvalenten Mangans recht häufig anzutreffen ist, wurde das rautenförmige Strukturmotiv des M2(μ‐O)2‐Kerns für M=Cu oder Fe erst vor kurzem in synthetischen Komplexen entdeckt. Die strukturelle und spektroskopische Charakterisierung dieser reaktiven Cu2(μ‐O)2‐ und Fe2(μ‐O)2‐Verbindungen wurde möglich durch die Verwendung von Hilfsliganden mit geeignetem Design, Methoden zur Handhabung bei tiefen Temperaturen und Messverfahren wie der Elektrospray‐Ionisierungs‐Massenspektrometrie un… Show more

“…Negative values of ∆G * showed spontaneous formation of the complexes [ 74 ]. The entropy change (∆S * ), which is a measure of disorder or randomness in the system, are negative, indicating that complex formation is favorable [ 5 ]. The enthalpy change is large and is enough to overcome the entropy change which favors the spontaneous formation of the complex [ 75 , 76 ].…”

“…Currently, the preparation of new copper complexes and investigation of their biological activities for pharmaceutical applications is one of the most dynamic fields. Copper(II) complexes have been found to be more potent than their parent ligands in biological activity [ 1 4 ] as well as in industrial applications [ 5 , 6 ]. The importance of mononuclear copper complexes also lies in the fact that these can possibly mime the active sites of metalloproteins such as the enzyme galactose oxidase [ 7 ] and nitrite reductase [ 8 ].…”

“…28,30,31 Monomeric nickel-oxo is very rare because of the tendency of the oxo and hydroxo ligands to form a bridge. 32 Metal complexes with terminal oxo 7,33 or hydroxo ligands have been implicated in various oxidative transformations, such as C–H bond functionalisation and oxo–transfer reactions. 34–36 Several bio-inspired catalysts have been probed as a catalyst for hydroxylation, sulfoxidation, and epoxidation.…”
