Radical allylation of vinyl perfluorocyclic sulfonamides leading to 1,1,2,2,3,3-hexafluorohex-5-ene-1-sulfonamides

Allylation reactions are essential for the introduction of alkene functionalities into molecules, and radical allylation reactions serve as a powerful strategy to achieve this. Of the various known allylating reagents, allyl bromides offer a particularly direct and efficient approach to allylation. Here, we report the radical allylation of vinyl perfluorocyclic sulfonamides using allyl bromides, which leads to the synthesis of allylated fluoroalkyl sulfonamides.
