Abstract

The carbon-sulphur bond in aliphatic diphenyldithio-acetals, α- carbonyldiphenyldithioacetals and α-carbonylketene dimethyldithioacetals can be cleaved cathodlcally on mercury (Hg) or glassy carbon (GC) electrodes. In the presence of tetra- butylammoniumhydrogensulphate (TBAHSO4) as a proton donor one thio-phenyl- respectively thiomethyl group is substituted by hydrogen to provide the corresponding ...
