Significance
A rhodium(III)-catalyzed desilylation of (trialkylsilyl)arenes with fluoride is reported, giving access to stabilized phenyl anion intermediates that eventually undergo addition to electrophiles. The desilylation is facilitated by the π-coordination of the rhodium complex.
#
Comment
Mechanistic as well as computational studies support the shown mechanism, involving nucleophilic addition of the fluoride to the aromatic ring, followed by 1,2-migration and C(sp2)–Si heterolysis.
