WebHazards The greatest hazard is formation of silver fulminate. To avoid formation of silver fulminate dispose of the Tollens' test immediately after performing the experiment. Silver … Diethylaminosulfur trifluoride (DAST) is the organosulfur compound with the formula Et2NSF3. This liquid is a fluorinating reagent used for the synthesis of organofluorine compounds. The compound is colourless; older samples assume an orange colour. See more DAST converts alcohols to the corresponding alkyl fluorides as well as aldehydes and unhindered ketones to geminal difluorides. Carboxylic acids react no further than the acyl fluoride (sulfur tetrafluoride effects … See more Upon heating, DAST converts to the highly explosive (NEt2)2SF2 with expulsion of sulfur tetrafluoride. To minimize accidents, samples … See more DAST is prepared by the reaction of diethylaminotrimethylsilane and sulfur tetrafluoride: Et2NSiMe3 + SF4 → Et2NSF3 + Me3SiF The original paper calls for trichlorofluoromethane (Freon-11) as a solvent, a compound … See more • Ishikawa reagent • Fluorination with aminosulfuranes See more
