  • 有机合成中间体;硅烷化试剂。

  • {ALF} In the presence of MeI, primary amines such as aniline are converted to their N,N-bis(trimethylsilyl) derivatives: J. Organomet. Chem., 510, 1 (1996), and ketones to silyl enol ethers in high yield: Organometallics, 16, 2204 (1997). The combination with an alkyl iodide or bromide also provides a convenient method for generating the iodo- or bromotrialkylsilane equivalent in ring-opening of cyclic ethers. With 1 mol of reagent the main product is the ω-siloxy alkyl halide; excess reagent affords the terminal dihalide: J. Org. Chem., 64, 8024 (1999).
  • {ALF} Moderately powerful silylating agent which functions as its own base (see Appendix 4). In the silylation of alcohols, the reagent is sensitive to steric effects. Thus, the equatorial hydroxyl group of 3-ß-tropanol can be silylated selectively: Acta Chim. Acad. Sci. Hung., 58, 189 (1968); J. Am. Chem. Soc., 96, 5876 (1974).
  • {ALF} Promotes direct 1,4-addition of ɑ-unsubstituted aldehydes to electron deficient olefins, specifically with enones to give δ-keto aldehydes: J. Chem. Soc., Perkin 1, 316 (2001). Alternative conditions were found to be ineffective.
