Selective Late‐Stage Sulfonyl Chloride Formation from Sulfonamides Enabled by Pyry‐BF(4)
Reported here is a simple and practical functionalization of primary sulfonamides, by means of a pyrylium salt (Pyry‐BF(4)), with nucleophiles. This simple reagent activates the poorly nucleophilic NH(2) group in a sulfonamide, enabling the formation of one of the best electrophiles in organic synth...
