Beschreibung

Allgemeine Beschreibung

XtalFluor-E^® is widely used in formylation, ring expansion, proto-functionalization, cyclodehydration, and dehydration.

Anwendung

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.

Sonstige Hinweise

The direct arylation of allylic sp³ C–H bonds via organic and photoredox catalysis
