Jr. Desmurs et al., SURPRISING CATALYTIC ACTIVITY OF BISMUTH(III) TRIFLATE IN THE FRIEDEL-CRAFTS ACYLATION REACTION, Tetrahedron letters, 38(51), 1997, pp. 8871-8874
Bismuth tris-trifluoromethanesulfonate (Bi(OTf)(3)) was found to be a
novel catalyst for the Friedel-Crafts acylation. The reactions of acti
vated or deactivated benzenes such as fluorobenzene proceeded in high
yields in the presence of a catalytic amount of BI(OTf)(3). This catal
yst is water stable and its catalytic activity is much higher than the
one of the other metallic triflates M(OTf)(3) previously reported (M
= Al, Ga, Ln or Sc). (C) 1997 Elsevier Science Ltd.
