Phenylselenium trichloride

Diphenyl diselenide has been prepared by disproportionation of phenyl selenocyanate in the presence of potassium hydroxide" or ammonia/ and by air oxidation of benzeneselenol. The preparation of benzeneselenol is described in an earlier volume in this series/ In the present procedure phenylselenomagnesium bromide formed from phenylmagnesium bromide and selenium is oxidized directly to diphenyl diselenide with bromine/ Thus the liberation of the malodorous and toxic hydrogen selenide and benzeneselenol is avoided. Benzeneselenenyl chloride has been prepared by thermal elimination of ethyl chloride from ethyl phenyl selenide di-chloride/ by thermal elimination of chlorine from phenylselenium trichloride," and by chlorinolysis of diphenyl diselenide with either sulfuryl chloride " or chlorine.

Thionyl chloride undergoes sonolysis at the S-Cl bond. The chlorine atoms react with bis(trialkylsilyl) ethers to give trialkylsilyl chlorides in good yields. A similar mechanism can be operative in the transformation of phenylselenous acid to phenylselenium trichloride, obtained in 88% yield in 15 min in pentane. ... [Pg.78]
