Properties
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.
form :Fuming Liquid
Specific Gravity :1.169
color :Clear colorless to light brown
Water Solubility :Miscible with dichloromethane, hydrocarbons, dialkyl ethers and halogenated solvents. Immiscible with water.
Sensitive :Moisture Sensitive
Hydrolytic Sensitivity :8: reacts rapidly with moisture, water, protic solvents
BRN :3590541
Stability :Moisture Sensitive and Hygroscopic, Moisture Sensitive And Hygroscopic

Description
Triethylsilyl trifluoromethanesulfonate acts as a silylating agent. It is also useful as a Lewis acid catalyst. Further, it reacts with 1-diazo-3,3-dimethyl-butan-2-one to prepare 1-diazo-3,3-dimethyl-1-(triethylsilyl)-2-butanone.More related product prices
