  An efficient fluorination of β-ketosulfones promoted by a room-temperature ionic liquid at ambient conditions under ultrasound irradiation using Selectfluor™ F-TEDA-BF4

  摘要：

  The fluorination reaction involving a beta-ketosulfones by Selectfluor (TM) was efficiently promoted by the ionic liquid, [Hbim]BF4 (IL) as a reaction medium with methanol as co-solvent at room temperature under ultrasonic irradiation to afford the corresponding mono and difluoro-beta-ketosulfones in excellent yields. The advantages of this method include among others the use of a recyclable, non-volatile ionic liquid, which promotes this protocol under room temperature without the requirement of any added catalyst under ultrasonic irradiation.

  Attempted fluorination of β-ketosulfides using Selectfluor™ resulted only in the isolation of the corresponding diaryl disulfides, presumed to arise by decomposition of an unstable fluorinated intermediate. However, fluorination of β-ketosulfones using Selectfluor™ under anhydrous conditions does allow the isolation of both mono-and difluorinated products in moderate to good yields.

  使用Selectfluor™尝试对β-酮硫醚进行氟化，仅导致了相应的二芳基二硫化物的分离，推测是由于不稳定的氟化中间体的分解而引起的。但是，在无水条件下使用Selectfluor™对β-酮砜进行氟化，确实能够以中等到良好的产率分离出单氟化和二氟化的产物。
