The electrolytic reduction of 1-methylsulfinyl-1-methylthio-2-arylethenes involves a cleavage of one carbon–sulfurbond, resulting in formation of E-1-methylthio-2-arylethenes in good yields, but not Z-isomers, in the presence of excess phenol as a proton donor.
In the electrolytic reduction of organic sulfur compounds of general formular (Remark: Graphics omitted.), the substrates with R=aryl are much easier to reduce than those with R=alkyl, and the former substrates afford the desulfinylated compounds, E-isomers of RCH=CH(SMe), in good yields, but the later substrates do not give the corresponding desulfinylated compounds.
