XtalFluor-E® and XtalFluor-M®: Convenient, Crystalline Deoxofluorination Reagents

This is an article regarding XtalFluor-E® and XtalFluor-M®: Convenient, Crystalline Deoxofluorination Reagents.

Francis Beaulieu et al.
Organic letters, 11(21), 5050-5053 (2009-10-06)
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
