A copper-catalyzed coupling reaction of sulfonyl chlorides with tertiaryamines via the oxidative C–N bond cleavage of tertiaryamines was developed. Sulfonamides were synthesized using this strategy in moderate to good yields. The reaction was applicable to various tertiaryamines, as well as sulfonyl chlorides.

Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flowsystem, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3CO2K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3] sources.
