Journal of the American Chemical Society, 2010•ACS PublicationsTrifluoromethyl-substituted superelectrophiles were generated in superacid (CF3SO3H),
and their chemistry was examined. The strong electron-withdrawing properties of the
trifluoromethyl group are found to enhance the electrophilic character at cationic sites in
superelectrophiles. This leads to greater positive-charge delocalization in the
superelectrophiles. These effects are manifested by the unusual chemo-, regio-, and
stereoselectivities shown by the superelectrophiles in chemical reactions.
