【Abstract】 The catalysts of rare earth(Ⅲ) perfluorooctanesulfonates (RE(OPf)3, RE=Sc,Y, La～Lu) have been prepared and synthesis of diarylketones by the Friedel-Crafts acylation on RE(OPf)3 catalysts in fluorous solvents were investigated. Perfluorodecalin (C10F18 , cis and trans-mixture) can be used as fluorous solvent for this reaction. By simple phase-separation the fluorous phase containing only catalyst could be re-utilized up to five times with a slight decrease in activity.
