Perfluoroethanesulfonyl fluoride: Preparation from sultone

A procedure was developed for preparing perfluoroethanesulfonyl fluoride by synthesis of hexafluoropropane-2-β-sultone from sulfuric anhydride and perfluoropropene, followed by hydrolysis of the sultone to α- tetrafluoroethanesulfonyl fluoride and fluorination of the latter with elemental fluorine.

Fluorosulfonation. Insertion of Sulfur Trioxide into Allylic C-F Bonds

Insertion of sulfur trioxide into allylic C-F bonds of both terminal and internal fluoro olefins is shown to form the most stable olefinic products.A mechanism involving fluoroallyl cations as intermediates is proposed.State-of-the-art ab initio calculations of the ground-state energies for two isomeric unsaturated fluoro ethers establish the slightly greater stability (5.7 kcal/mol) of a vinyl ether over the corresponding fluoro olefin.A description of the optimized geometries of these molecules is also presented.
