What is Diethylaminosulfur Trifluoride ?
Diethylaminosulfur Trifluoride (DAST) is a widely used fluorination reagent in organic synthesis. It is a member of the (dialkylamino) sulfur trifluoride family. DAST is a nucleophilic fluorination reagent, which can convert hydroxyl compounds to monofluorinated compounds, aldehydes and ketones to difluorinated compounds, and has no effect on the carbonyl groups of carboxylic acids and their derivatives.

Application of Diethylaminosulfur Trifluoride
Diethylaminosulfur Trifluoride is a liquid that can be stored for a long time at room temperature or in the refrigerator under dry conditions. DAST will decompose at 90 ° C, and there is a risk of explosion if it is not handled properly. However, Diethylaminosulfur Trifluoride because of its simplicity and versatility, DAST is one of the most widely used fluororeagents. Physical properties Diethylaminosulfur Trifluoride is a brown yellow liquid with a boiling point of 30~32ºC/3.0mmHg and a density of 1.220g/cm3. Soluble in most non-polar organic solvents, commonly used in CH2Cl2, CHCl3, and CCl4.
Function of Diethylaminosulfur Trifluoride
Diethylaminosulfur Trifluoride (DAST) is used as fluorination reagent and fluorination agent on anticancer drugs. For example, it reacts with alcohols to obtain corresponding fluoroalkanes; Reacting with acyl chloride to obtain the corresponding acyl fluoride; The reaction with aldehydes or ketones produces twinned difluoride; It reacts with sulfoxide to get α-fluorosulfoxide, and then oxidizes with perchlorobenzoic acid to get α-fluorosulfoxide.
