Katritzky salts are used as the alkyl radical precursors with the insertion of sulfur dioxide under photoredox catalysis. This transformation first enables direct generation of various alkylsulfonyl radicals by photoinduced single electron reduction, leading to diverse dialkyl sulfones in good to excellent yields. A radical pathway is proposed under visible-light induced conditions with the insertion of sulfur dioxide.

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

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.
