The introduction of an organothio group to an α-carbon of ethers results in significant decrease of the oxidation potentials. Anodic oxidation of α-organothioethers gives rise to facile cleavage of the C-S bond and the introduction of carbon nucleophiles on the carbon. Allylsilanes, silyl enol ethers, and trimethylsilyl cyanide serve as effective carbon nucleophiles. The anodic oxidation of the α-organothioethers having a carbon-carbon double bond in an appropriate position using Bu4-NBF4 as the supporting electrolyte leads to the effective cyclization and the introduction of the fluoride to one of the formal olefinic carbon. The present study demonstrates the effectiveness of organothio groups as electroauxiliaries in electrooxidative inter- and intramolecular carbon-carbon bond formation.
