Description
Summary:A simple continuous flow process for aerobic oxidation of benzylic organotrifluoroborates salt by photoredox catalysis under UV irradiation is reported. Using this approach benzylic organotrifluoroborates salts could be easily oxidized to the corresponding benzaldehydes. Good to excellent yields were obtained by applying short residence times in combination with molecular oxygen as oxidant under Taylor flow configuration.
