A useful synthesis of ω-iodoperfluoroalkanesulfonyl fluorides and perfluoroalkane-α,ω-bis-sulfonyl fluorides
摘要:
Omega-iodoperfluoroalkanesulfonyl fluorides and perfluoroalkane-alpha,omega-bis-sulfonyl fluorides have been prepared via deiodosulfination, chlorination, and then chlorine-fluorine exchange reaction of alpha,omega-diiodoperfluoroalkanes I(CF2)nI (n=3, 4, 6). Similar reaction of I(CF2)2O(CF2)2SO2F affords FSO2(CF2)2O(CF2)2SO2F.
