  • A useful component of Ziegler-Nattametallocene catalyst for polyolefins.
  • {ALFA} Air-stable, water-tolerant Lewis acid; for a review, see: Chem. Soc. Rev., 26, 345 (1997). Introduced by Yamamoto as a catalyst (2 mol%) for aldol condensations between silyl enol ethers and aldehydes under extremely mild conditions at temperatures between -78o and ambient. Also effective for Michael additions of silyl enol ethers with enones: Synlett, 577 (1993). Low-temperature condensation of ester enol silanes with imines provides a route to ß-amino esters: Synlett, 963 (1994). Superior catalyst to TBAF for O-silylation with trialkyl or triaryl silanes. Alcohols and phenols are silylated using 2-8 mol% catalyst, with secondary and tertiary alcohols reacting faster than primary: J. Org. Chem., 64, 4887 (1999). Effective catalyst for reduction with Triethyl­silane, A10320, of alcohols and ethers to alkyls: Tetrahedron Lett., 40, 8919 (1999). Catalyst for highly efficient hydrosilylation of olefins with silanes R3SiH: J. Org. Chem., 67, 1936 (2002).

  • {ALFA} Catalyst for regioselective rearrangement of epoxides to carbonyl compounds: Synlett., 721 (1995), and efficient cleavage of epoxides with allyl and propargyl alcohols, amines and thiols: Tetrahedron Lett., 43, 3801 (2002).
