TRIFLUOROMETHYLATION AND PENTAFLUOROPHENYLATION OF SULFUR AND CARBON CENTERS USING (TRIFLUOROMETHYL)-TRIMETHYLSILANE AND (PENTAFLUOROPHENYL)TRIMETHYLSILANE

Trifluoromethyl and pentafluorophenyl moieites are easily transferred to a variety of fluorinated inorganic and organic sulfur and carbon centers by using (trifluoromethyl)trimethylsilane and (pentafluorophenyl)trimethylsilane in the presence of catalytic amounts of fluoride ion. This methodology is readily applied to the simple, efficient preparation of known, previously difficult to obtain molecules, as well as a number of new perfluoroalkyl and perfluoroaryl sulfuranes, sulfoxides, ketones, esters, and alcohols. In addition, the first stable oxysulfurane containing more than two sulfur-carbon bonds has been prepared.
