(author)Biocatalytic oxidation reactions of toluene derivates to the corresponding aldehydes are typically challenged by regio- and chemoselectivity issues. In this contribution we address both challenges by a combined reactant- and reaction engineering approach. We demonstrate that the peroxygenase-catalysed transformation of ring-substituted...journal article 2023

(author), Holtmann, Dirk (author)Various enzymes utilize hydrogen peroxide as an oxidant. Such “peroxizymes” are potentially very attractive catalysts for a broad range of oxidation reactions. Most peroxizymes, however, are inactivated by an excess of H<sub>2</sub>O<sub>2</sub>. The electrochemical reduction of oxygen can be used as an in situ generation method for hydrogen...journal article 2019

(author), Bormann, Sebastian (author), Alcalde, Miguel (author), Holtmann, Dirk (author), Hollmann, F. (author)Photoenzymatic cascades can be used for selective oxygenation of C−H-Bonds under mild conditions circumventing the hydrogen peroxide mediated peroxygenase inactivation via in situ H<sub>2</sub>O<sub>2</sub> generation. Here, we report the “on demand” production of hydrogen peroxide via methanol assisted reduction of molecular oxygen using UV...journal article 2019
