Wu, Bin (author), Wang, Xiangyun (author), Yang, Bo (author), Ma, Yunjian (author), Hollmann, F. (author), Wang, Yonghua (author)In the present work we propose a bienzymatic cascade for the oxyfunctionalisation of cycloalkanes to cyclic alcohols/cyclic ketones. By combining a H<sub>2</sub>O<sub>2</sub>-dependent peroxygenase with a O<sub>2</sub>-consuming and H<sub>2</sub>O<sub>2</sub>-producing alcohol oxidase an overall aerobic oxidation system was established. A...journal article 2023
