Abstract
Abstract The electrolytic reduction of (E)-1-methylsulphinyl-1-methylthio-2-phenylethene ( 1 ) in acetonitrile involves selective cleavage of one carbon-sulphur bond, resulting in formation of (E)-1-methylthio-2-phenylethene ( 2 ) in good yields, but not the (Z)-isomer, in the presence of excess phenol and benzoic acid, respectively, as proton donor and at all the following electrodes; mercury, platinum, lead, and glassy carbon. Polarographic studies of 1 and its related compounds such as 1,1-dimethylthio-2-phenylethene ( 3 ), (E)-1-methylsulphinyl-2-phenylethene ( 4 ), and 2 has revealed that the electrolytic reduction of 1 to 2 proceeds via neither 3 nor 4 , but via elimination of the methylsulphinyl group.
