The fluorination reaction involving a β-ketosulfones by Selectfluor 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.

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.
Hydantoin derivatives as potential antiinflammatory agents

The hydantoins 2a-c and three hydantoic acids were synthesized and their anti-inflammatory properties were determined in the rat paw oedema test. Neither 1-phenyl-sulphonyl-5,5-diphenylhydantoin, which has been described as an inflammatory, nor any of the other compounds, showed significant anti-inflammatory activity.
