Abstract

Lanthanide(lll) salts of superacids, such as trifluoromethanesulfonicacid, perfluorooctanesulfonic acid and perchloric acid, can be readily prepared as stable solids (except perchlorate). Some of these work as novel water-tolerant Lewis acids to catalyze various types of organic reactions. The combined use of a lanthanide(lll) salt of superacid with an optically active ligand provides a special environment for an asymmetric Diels-Alder reaction. New chiral nonracemic lanthanide(lll) salts of (R)-(-)-1,1'-binaphthyl-2,2'-diylphosphoric acid were synthesized and used for a hetero-Diels-Alder reaction.
