• -doped diamond electrode; electrosynthesis; oxidation; Introduction Selective oxidation of aromatic alkyl side chains is an important molecular transformation process to obtain various rubbers, resins, fine chemicals, and other industrial products [1][2]: terephthalic acid from p-xylene, cumene

• , where the BDD’s wide potential window enables the direct anodic oxidation of cumene into the cumyl cation. Since electricity is directly employed as the oxidizing and reducing reagents, the present protocol is easy to use, suitable for scale-up, and inherently safe. Keywords: aromatic alkyl; boron
