Diethylaminosulfur trifluoride (DAST) has proven itself to be an extremely popular reagent for nucleophilic fluorination, due to its ease of handling and versatility. It has regularly been employed in a myriad selective fluorinations of alcohols, alkenols, carbohydrates, ketones, sulfides, epoxides, thioethers, and cyanohydrins. In addition some novel organic cyclizations are possible when DAST is employed as a reagent.
