XtalFluor-E Chemical Properties,Usage,Production

Description

XtalFluor-E, [Et2NSF2]BF4, is best known as a useful, versatile and inexpensive commercially available reagent for the deoxyfluorination of carbonyl compounds and alcohols. Although XtalFluor-E is commonly used in combination with an exogenous fluoride source as a deoxofluorinating reagent, it has also been widely employed in other chemical transformations such as dehydration, cyclodehydration, ring expansion, formylation, and proto-functionalization, etc.

Uses

XtalFluor-E can be used as convenient crystalline highly chemoselective deoxofluorination reagent with a broad substrate scopeDeoxofluorination reagent with a better safety profile.

Application

Convenient crystalline highly chemoselective deoxofluorination reagent with a broad substrate scope
Deoxofluorination reagent with a better safety profile, that doesn′t generate corrosive HF which makes it suitable for use in standard borosilicate vessels, and does not react violently with water
Reactant for:
Preparation of fluorodisaccharides
Triisopropylsilanethiol was recently reported by MacMillian and coworkers to be used as an organocatalyst, in tandem with Ir(III) specifically Aldrich product 688096, in photoredox catalysis. This approach directly couples a cyano-containing arene with an allylic sp3 C-H bond.
