Rare earth(III) perfluorooctane sulfonates (RE(OPf)3) catalyze the efficient aldol condensation of different ketones with various aromatic aldehydes in fluorous solvents without the occurrence of any self-condensations. By simple separation of the fluorous phase containing only catalyst, reaction can be repeated several times.
