Abstract

The synthesis of sulfonyl fluorides via the reaction of sulfonyl hydrazides and Et3N·3HF under electrochemical conditions is reported. Various sulfonyl fluorides were obtained in good yields under a constant current of 15 mA for 10 h in CH2Cl2/DMSO. It was found that n-Bu4NI acts as an electrolyte and a redox catalyst to produce sulfonyl radical species from sulfonyl hydrazides.
