BeschreibungLanthanum trifluoromethanesulfonate is a Lewis acid catalyst useful for aldol, Michael, Diels-Alder, and other C-C bond forming reactions; also useful for preparing organolanthanum reagents, which react with hindered tertiary amides to afford ketones.

VerwendenLanthanum trifluoromethanesulfonate is a water-tolerant Lewis acid used in the Aldol reaction of silyl enol ethers with aldehydes. It is an effective catalyst for the Baylis-Hillman reaction. It also catalyzes Michael additions to methyl vinyl ketone in water.
