(Trifluoromethyl)trimethylsilane Chemical Properties,Uses,Production

Chemical Properties

clear colorless solution

Uses

Nucleophilic addition of the trifluoromethyl group to aldehydes and ketones.1

Uses

Nucleophilic trifluoromethylating reagent.

Purification Methods

Purify it by distilling it from trap to trap in a vacuum of 20mm using a bath at 45o and Dry-ice/Me2CO bath for the trap. The liquid in the trap is then washed with ice cold H2O (3x), the top layer is collected, dried (Na2SO4), and the liquid is decanted and fractionated through a helices-packed column at atmospheric pressure. 1H, 1 3C, 1 9F, and 2 9Si NMR can be used for assessing the purity of fractions.
