Abstract: The addition of <i style="">p</i>-methylbenzenethiol to <i style="">p</i>-tolyl­phenyl­acetylene results in the formation of a mixture of diastereomeric (<i style="">E</i>) & (<i style="">Z</i>)-1-(4-methylphenyl)-2-phenyl-1-[(4-methyl­phenyl)thio] ethylenes (<b>1</b> and <b>2</b>) and (<i style="">E</i>) & (<i style="">Z</i>)-2-(4-methylphenyl)-1-phenyl-1-[(4-methylphenyl)thio] ethylenes (<b>3</b> and <b>4</b>). The configurations of these compounds have been established by <sup>1</sup>H NMR studies, by their preparation from benzyl <i style="">p</i>-tolyl ketone and <i style="">p</i>-methylbenzyl phenyl ketone, and by the oxidation of the thioethylenes <b>1</b>, <b>2</b>, <b>3</b> and <b>4</b> to the corresponding sulfonylethylenes <b>5</b>, <b>6</b>, <b>7</b> and <b>8</b> respectively.
