Benzylic Intermolecular Carbon−Carbon Bond Formation by Selective Anodic Oxidation of Dithioacetals

Novel anodic intermolecular carbon−carbon bond formation has been accomplished by the oxidative carbon−sulfur bond fission of benzylic dithioacetals to give a wide variety of aromatic compounds. The substitution reaction successfully took place by the selective anodic oxidation of a sulfur atom of a dithioacetal. Stepwise double-substitution reactions were also achieved by the regulation of oxidation potential.
