Imikoreshereze
Diethylamino-sulfur trifluoride (DAST) ni reagent ya fluorination ikoreshwa cyane mu guhuza organic. Ni kimwe mu bigize umuryango wa (dialkylamino) sulfur trifluoride. DAST ni reagent ya fluorination ya nucleophilic, ishobora guhindura itsinda rya alcohol hydroxyl mo fluorine na aldehydes na ketones muri difluoride.
