(<I>E</I>)-1-Aryl-2-(methylsulfinyl)-2-(methylthio)ethene, obtained by the Knoevenagel-type condensation of methyl (methylthio) methyl sulfoxide with the corresponding aromatic aldehyde, was found to react with ethylmagnesium chloride to give (<I>Z</I>)-1-aryl-2-(methylthio)ethene predominantly. Since the reaction of (<I>Z</I>)-1-(methylsulfinyl)-1-(methylthio)-2-phenylethene afforded (<I>E</I>)-1-(methylthio)-2-phenylethene, the present reaction appeared to be stereospecific.
