A catalytic CC bond‐forming reaction between aliphatic fluorohydrocarbons and arylsilanes

Abstract

Abstract CC coupling reactions between arylsilanes and alkylfluorides are efficiently catalyzed by disilyl cation 1. Primary as well as secondary alkylfluorides were quantitatively coupled with arylsilanes; however, in the case of tertiary fluorides, the hydrodefluorination reaction predominated. Primary alkylfluorides were found to give arenes with mostly rearranged alkyl substituents. In all cases subsequent Friedel–Crafts‐type chemistry occurred. Copyright © 2010 John Wiley & Sons, Ltd.
