Electrochemical Radical Fluorosufonylation of Allyl Bromides

A radical fluorosulfonylation of allyl bromides was achieved under electroreductive conditions. This catalyst-free protocol employs mild conditions and enables straightforward access to a new and structurally diverse variety of previously inaccessible allyl sulfonyl fluorides. We have also illustrated the synthetic value of this method by performing scaled-up reactions and product derivatization.
