Usus
Trifluoridum diethylaminosulfuris (DAST) est reagens fluorinationis late adhibitum in synthesi organica. Est membrum familiae trifluoridi (dialkylamino)sulfuris. DAST est reagens fluorinationis nucleophilicum, quod potest convertere gregem hydroxylum alcoholis in fluorinum correspondens et aldehydas et cetonas in difluoridum.
