- 中文摘要: A 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-alkanesulfeneyl-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 b addition of the corresponding sulfonyl iodides to phenylacetylene under the catalytic action of cupric chloride and triethylaminium chloride.
