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.

Oxalic acid catalyzes a reaction between dithioacetals and acetals. This reaction is useful in a new and eco-friendly method to convert dithioacetals to carbonyl compounds.

It was found that oxidation potentials of methanes with ?-electron substituents were decreased by introduction of a trimethylsilyl group.The anodic oxidation of benzyl-, allyl-, aryl(or alkyl)thiomethyl-, and aryloxymethyl-substituted trimethylsilanes smoothly proceeded in the presence of nucleophiles, e.g. alcohols and carboxylic acids, to eliminate the trimethylsilyl groups giving the corresponding alkoxylated and carboxylated products in moderate or high yields without full optimization of electrolytic conditions, while aminomethylsilanes did not undergo such a kind of anodic oxidation.
