hydrogen fluoride at 60° to yield 1,2,2,2-tetrafluoroethanesulphonyl fluoride. The last product is also obtained by treatment of perfluoroethylenesulphonyl fluoride with anhydrous potassium fluoride in formamide at 35°. Thus the olefin is polarised in the sense [graphics omitted]·SO2F. The compounds CF2Br·CHF·SO2F, CF2Br·CFBr·SO2F, and CF2Cl·CFCl·SOF are obtained in high yield by free-radical hydrobromination
