Patent ID: 8377406

Claim:
A method for producing a fluorinated compound of the formula: F—S(O) 2 —Z—S(O) 2 —F from a nonfluorohalide compound of the formula: X—S(O) 2 —Z—S(O) 2 —X, said method comprising contacting said nonfluorohalide compound with BiF 3 under conditions sufficient to produce said fluorinated compound and BiX 3 as a byproduct, wherein each X is independently a halide, provided at least one of X is a non-fluoro halide; Z is NR 1 or CR 2 R 3 ; R 1 is H, alkali metal, alkyl, or a nitrogen protecting group; and each of R 2 and R 3 is independently H, halide, alkyl, or haloalkyl.
