AbstractA convenient synthesis for varions (Z)‐1‐alkanesulfinyl‐2‐phenylethenes has been developed. This involves addition of different sodium thiolates to phenylacetylene in ethanol, and oxidation of the resulting (Z)‐1‐alkanesulfenyl‐2‐phenylethenes [(Z)‐styryl alkyl thioethers] with sodium metaperiodate supported on acidic alumina. The corresponding sulfones can be obtained by oxidation of these (Z)‐styryl alkyl thioethers with hydrogen peroxide in glycial acetic acid, or, alternatively by reduction of the β‐iodostyrylsulfones with zinc in acetic acid. These β‐iodostyrylsulfones were obtained by addition of the corresponding sulfonyl iodides to phenylacetylene under the catalytic action of cupric chloride and
