The photocatalytic oxidation of mono- and di-substituted arylboronic acids to phenols has been investigated using a continuous flow photoreactor fitted with white LEDs. An EtOH–H 2 O solvent system accelerated conversion at 2 MPa; whereas reactions at atmospheric pressure allowed for moderately effi...
