Triethylsilyl trifluoromethanesulfonate Property
  • Boiling point: :85-86 °C/12 mmHg (lit.)
  • Density  :1.169 g/mL at 25 °C (lit.)
  • refractive index  :n20/D 1.389(lit.)
  • Flash point: :162 °F
  • storage temp.  :Inert atmosphere,Room Temperature
  • solubility  :Triethylsilyl Trifluoromethanesulfonate is readily sol hydrocarbons, dialkyl ethers, halogenated solvents. CH2Cl2 is employed most commonly. Reactions in 1,2-dichloroethane proceed faster than those in CCl4 or Et2O. Protic solvents and THF react with trialkylsilyl triflates and are therefore not suitable.

Triethylsilyl trifluoromethanesulfonate Chemical Properties,Usage,Production

  • Chemical Properties clear colorless to light brown fuming liquid
  • Physical properties 85–86 °C/12 mmHg; d 1.169 g cm?3.
  • Uses Triethylsilyl Trifluoromethanesulfonate can be used as potent silylating agent and as Lewis acid catalyst. Triethylsilyl ethers are generally more stable towards hydrolysis than are trimethylsilyl ethers, and consequently the Et3Si moiety has gained increasing use as a protecting group for alcohols. However, since it is often difficult to silylate sterically hindered hydroxyl groups using Et3SiCl, triethylsilyl perchlorate and triethylsilyl triflate (Et3SiOTf) were introduced to overcome this problem. Jefford has reported that condensation reactions of 2-trimethylsiloxyfuran with aldehydes can be catalyzed by Et3SiOTf to give mainly the threo addition product (eq 8).
  • Preparation Triethylsilyl Trifluoromethanesulfonate can be prepared by reacting chlorotriethylsilane with trifluoromethanesulfonic acid followed by distillation.
