A protocol for the preparation of a fluorous arylselenenyl chloride is described. This selenenyl chloride may be used for the direct alpha-selenation of ketones and, following oxidation and syn-elimination, formation of alpha,beta-unsaturated carbonyl compounds. Treatment of the crude reaction mixtures with sodium metabisulfite reduces the various selenium species to the diaryl diselenide, which is
