Abstract

The preparation of a variety of novel perfluoroalkyl-substituted compounds in high yields using easily prepared (perfluoroalky1) trimethylsilanes (la-c) is described.(Trifluoromethy1)- ,(pentafluoroethy1)-, and (hepta-fluoropropyl) trimethylsilane, la-c, respectively, react readily with carbonyl compounds, such as aldehydes and ketones, by a fluoride-initiated catalytic process. Fluoride-initiated addition of 1 to a carbonyl group generates an oxyanionic ...
