Preparation

(2-phenylsulfonylethyl)trimethylsilane (2) is prepared by radical addition of thiophenol to vinyltrimethylsilane to give (2-phenylthioethyl)trimethylsilane (1), which is then oxidized with hydrogen peroxide).

Purification Methods

Dissolve it in Et2O, wash it with saturated HCO 3 followed by saturated NaCl, H2O and dried (MgSO4). Evaporation leaves residual crystals with m 52o. [Hsiao & Shechter Tetrahedron Lett 23 1963 1982, Bortolini et al. J Org Chem 53 2688 1985.]

Sulfone reagents in organic synthesis. VI. Sulfonyl- and silyl-substituted hydrocarbons as versatile carbanion precursors in organic synthesis

The basic organometallic chemistry of β-silyl-substituted acetylenic, vinylic and alkyl sulfones has been investigated, with attention being given to metallation, carbometallation and the chemical reduction of carbon-carbon unsaturation. 2-Trimethylsilylvinyl and 2-trimethylsilylalkyl sulfones underwent smooth and stereoselective lithiation with RLi on the carbon α to the sulfonyl group. Carbometallation of vinyl sulfones could be achieved with RMgX or LiCuR2, but acetylenic sulfones carbometallated smoothly only with LiCuR2; with RMgX or RLi, these acetylenes underwent alkyldesulfonylation. The utility in synthesis of these metallo derivatives of sulfonyl-silyl-hydrocarbons is discussed and their value in elaborating carbon skeletons is illustrated for the preparation of alkenes, allenes, carbocycles and stereo-defined vinyl sulfones.
