Electrochemical analyses of 4,4,5,5-tetramethyl-2-phenylsulfanylmethyl-[1,3,2]dioxaborolane and tetra-n-butylammonium phenylthiomethyltrifluoroborate were comparatively studied by cyclic voltammetry measurements and we found for the first time the β-effect of organoborate, which was indicated by experimental and theoretical aspects. The organoborate was found to have a much lower oxidation potential compared to the organoborane. Anodic substitution reaction of organoboronate ester and organoborate was successfully carried out in the presence of nucleophiles to afford the selectively substituted products in good yields.

One-pot synthesis of dithioacetals as well as an efficient method for oxathioacetal is reported. Additionally, some chiral auxiliaries were used to synthesize enantiomerically pure dithioacetals and oxathioacetals.

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.
