Palladium-catalyzed electrochemical C(sp)-H acetoxylation to prepare 1,2-diol derivatives was achieved using oxime ethers as -directing groups. Various substrates containing alkoxy groups with a methyl branch at the α-position as well as norbornan-2-ol derivative were acetoxylated only using a catalytic amount of Pd(OAc) along with NaOAc/AcO/AcOH under anodic oxidation conditions.
