A copper‐mediated di‐ and monofluoromethanesulfonylation of arenediazoniumtetrafluoroborates using di‐ and monofluoromethanesulfinate reagents provides aryl difluoromethyl (or monofluoromethyl) sulfones in good yields. It was found that the relative reactivity of these sodium fluoroalkanesulfinates in the present reactions decreases in the following order: CH2FSO2Na > CF2HSO2Na > CF3SO2Na.
