Kev Siv
Diethylamino-sulfur trifluoride (DAST) yog ib qho tshuaj fluorination reagent siv dav hauv cov organic synthesis. Nws yog ib tug tswv cuab ntawm (dialkylamino) sulfur trifluoride tsev neeg. DAST yog ib qho nucleophilic fluorination reagent, uas tuaj yeem hloov cov cawv hydroxyl pawg mus rau hauv cov fluorine thiab aldehydes thiab ketones mus rau hauv difluoride.
