Descrição geral

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

Aplicação

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.

The selective introduction of fluorine onto the skeleton of an aminocyclopentane or cyclohexane carboxylate has been developed through a novel and efficient fluoride opening of an activated aziridine ring with XtalFluor-E. The reaction proceeded through a stereoselective aziridination of the

Aminodifluorosulfinium tetrafluoroborate salts were found to act as efficient deoxofluorinating reagents when promoted by an exogenous fluoride source and, in most cases, exhibited greater selectivity by providing less elimination byproduct as compared to DAST and Deoxo-Fluor. Aminodifluorosulfinium tetrafluoroborates are easy
Alexandre L'heureux et al.
The Journal of organic chemistry, 75(10), 3401-3411 (2010-04-22)
Diethylaminodifluorosulfinium tetrafluoroborate (XtalFluor-E) and morpholinodifluorosulfinium tetrafluoroborate (XtalFluor-M) are crystalline fluorinating agents that are more easily handled and significantly more stable than Deoxo-Fluor, DAST, and their analogues. These reagents can be prepared in a safer and more cost-efficient manner by avoiding
