Abstract
We develop a rapid and mild protocol to access sulfonimidoyl fluoride-[S(VI)] from sulfenamide-[S(II)] directly. The transformation occurs via the reaction of sulfenamide with NCS (N-chlorosuccinimide), water, and TBAF in acetonitrile. Water and TBAF act as the source for S═O bond formation and fluoride, respectively. The reaction takes a very short time (within 5 min). The drug molecules, such as Carbamazepine and Levetiracetam attached sulfonimidoyl fluorides are also achieved following this protocol. Furthermore, sulfonimidoyl fluoride is transformed into sulfonimidamide in the presence of AlCl3. To the best of our knowledge, it is the first report detailing the synthesis of sulfonimidoyl fluoride-[S(VI)] directly from S(II)-sulfenamide.
