Unspecific peroxygenases (UPOs) are promising biocatalysts for oxyfunctionalisation reactions, owing to their simplicity of handling, stability and robustness. A limitation using UPOs on a large scale is deactivation in the presence even rather modest concentrations H2O2, requiring constant controlled supply low amount H2O2. Herein, we report an organometallic complex [Cp*Ir(pica)NO3] {pica=pic...

The cytochrome P450 enzyme superfamily (CYP), E.C. 1.14.-.-, are haem-containing monooxygenases with a vast range of both endogenous and exogenous substrates. These include sterols, fatty acids, eicosanoids, fat-soluble vitamins, hormones, pesticides carcinogens as well drugs. Listed below the human enzymes, their relationship rodent CYP activities is obscure in that species orthologue may not ...

The new cis-dioxomolybdenum (VI) complexes [MoO2(L2)(H2O)] (2) and [MoO2(L3)(H2O)] (3) containing the tridentate hydrazone-based ligands (H2L2 = N'-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-methylbenzohydrazide H2L3 N'-(2-hydroxybenzylidene)-2-(hydroxyimino)propanehydrazide) have been synthesized characterized via IR, 1H 13C NMR spectroscopy, mass spectrometry, single crystal X-ray diffraction...

This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. A variety of dihydroflavins were prepared and the electrochemical oxidation potentials were measured and compared with their catalytic ...
