Allylation of 1,3-dicarbonyl compounds with allylic alcohols was successfully accomplished using rare earth metal (III) bis(perfluorooctanesulfonyl)imide [RE(NPf(2))(3), RE= La similar to Lu] as catalysts in fluorous solvents. Ytterbium bis(perfluotooctanesulfonyl)imide [Yb(NPf(2))(3)] catalyzes the high efficient reaction of allylation in fluorous solvents. By simple separation, fluorous phase containing only catalyst can be reused several times. (c) 2009 Elsevier B.V. All rights reserved.
