(Diethylamino)difluorosulfonium tetrafluoroborate(Xtalfluor-E,DAST difluorosulfinium salt) is a convenient crystalline highly chemoselective reagent for nucleophilic (deoxo)fluorination with a broad substrate scope and better safety profile like: air stable solid, enhanced thermal stability than DAST or DeoxoFluor, compatibility with glass due to no-generation of free HF under anhydrpous conditions, and simple work-up procedure, etc..
