Several 9-arylxanthylium tetrafluoroborate salts (Ar=H, p,m-F, p,m-Me, m-OMe) were synthesized by reaction of the corresponding 9-arylxanthen-9-ol with fluoroboric acid.Spectral characteristics of the xanthyl cations were identical to those previously rep
Electrophilic Reactions of Xanthylium Carbocations Produced by Flash Photolysis of 9-Xanthenols

The xanthylium ion and eight 9-aryl derivatives (p-MeO, p-Me, m-Me, H, p-F, m-MeO, p-Cl, and p-CF3 phenyl) were produced in 1:4 acetonitrile/water by flash photolysis of the corresponding 9-xanthenols.The identifications of the transients as xanthylium ca
