substitution of the phenyl group with a hydroxy group took place smoothly to afford alkenylsilanol derivatives in good yields. The reaction mechanism was investigated using 18 O-labeled sulfoxide. We found that a (methylsulfinyl)methyl anion generated from DMSO participated in this reaction.

On treatment of allyl-t-butyldiphenylsilane with t-BuOK and 18-Crown-6 in DMSO at room temperature, isomerization of the olefinic double bond and subsequent substitution of phenyl group with hydroxy group took place smoothly to afford alkenylsilanol derivatives in good yields.
