An efficient fluorination of β-ketosulfones promoted by a room-temperature ionic liquid at ambient conditions under ultrasound irradiation using SelectfluorTM F-TEDA-BF4
摘要:
The fluorination reaction involving a β-ketosulfones by SelectfluorTM 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-β-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.
