• Water-tolerant and potentially reusable Lewis acid catalyst in a wide variety of reactions. The use of rare earth metal triflates in organic synthesis has been reviewed by S. Kobayashi: Synlett, 689 (1994); Chem. Rev., 102, 2227 (2002). Applications include:
• Aldol reactions of silyl enol ethers in aqueous media: J. Org. Chem., 59, 3590 (1994); Bull. Chem. Soc. Jpn., 67, 2342 (1994); or in organic solvents: Synthesis, 371 (1993). Friedel-Crafts acylations: J. Chem. Soc., Chem. Commun., 1157 (1993). Allylation of aldehydes: Bull. Chem. Soc. Jpn., 67, 2342 (1994). Mannich reactions: J. Chem. Soc., Chem. Commun., 1379 (1995). Hetero Diels-Alder reactions: J. Chem. Soc., Chem. Commun., 1195 (1995). Catalyzes Michael additions to methyl vinyl ketone in water. The reaction rate is dramatically increased (up to 20-fold) by the addition of a catalytic amount of N,N,N',N'-Tetramethyl­ethyl­enediamine, A12536: J. Org. Chem., 71, 352 (2006).
