Reaction of the Lewis Acid Tris(pentafluorophenyl)borane with a Phosphorus Ylide:  Competition between Adduct Formation and Electrophilic and Nucleophilic Aromatic Substitution Pathways

Treatment of the phosphorus ylide Ph3PCH2 (2a) with B(C6F5)3 (1) yields the adduct Ph3P+−CH2−B(C6F5)3 - (3a), which was characterized by X-ray crystal structure analysis. The ylide Ph3PCHPh (2b) reacts analogously with B(C6F5)3 at 0 °C to form Ph3P+−CHPh−B(C6F5)3 - (3b), but this adduct formation...
