Abstract
The lanthanoide trifluoromethanesulfonate (lanthanoid triflate)-cataly zed aldol reactions of silyl enol ethers with aldehydes and allylation reactions of tetraallyltin with aldehydes processded smoothly in a wa ter-ethanol-toluene system. The reactions proceeded much faster in the above solvent than in water-tetrahydrofuran. Repeated use of the cata lyst in these reactions was realized by a very simple procedure.
