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