The title group has been used as a maskedhydroxylgroup, allowing a mild and high yielding oxidation of the CSi bond. Its use in various transformations demonstrates its chemical stability as well as its ability to be transformed into the corresponding OH group even in the presence of sensitive functionalities.

The α-dimethyl(1-phenylthio)cyclopropylsilylgroup was used as a new masked hydroxy group. Three procedures have been devised to allow the oxidation of this silicon group in the presence of various functionalities. The desired alcohols are obtained in high yields with retention of configuration at the carbon centre.
