Perfluorosulfonyl chloride

Perfluorosulfonyl chloride or sulfonic acid group can be desulfonylated under various conditions, to prepare a carboxylic acid group. 

Perfluoroalkyl radicals can be generated from perfluorosulfonyl chloride using RuCljCRPh,), as a catalyst. In the presence of 1-substituted pyrroles good yields of 2-perfluoroalkylpyrroles were obtained with N-substituents such as acetyl, benzenesulfonyl or trimethylsilyl. With tr/s-isopropylsilyl, however, 3-substitution was preferred. <94SC2049, 94JCS(P1)1339>... 

Electrochemical fluorination of alkanesulfonyl chlorides or fluorides yields the corresponding perfluorosulfonyl chloride or fluoride in a 12-79% yield, depending on the alkane chain length [51] ...
