1. 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 BiF3 under conditions sufficient to produce said fluorinated compound and BiX3 as
1. 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 BiF3 under conditions sufficient to produce said fluorinated compound and BiX3 as a byproduct, wherein each X is independently a halide, provided at least one of X is a non-fluoro halide;Z is NR1 or CR2R3;R1 is H, alkali metal, alkyl, or a nitrogen protecting group; andeach of R2 and R3 is independently H, halide, alkyl, or haloalkyl. 2. The method of claim 1 further comprising the step of contacting BiX3 with an oxygenating agent under conditions sufficient to produce Bi2O3. 3. The method of claim 2, wherein said oxygenating agent comprises a metal carbonate, a hydroxide compound, water, oxygen, ozone, hydrogen peroxide, nitrous oxide, osmium tetraoxide, or a combination thereof. 4. The method of claim 3 further comprising the step of contacting Bi2O3 with a fluorinating agent under conditions sufficient to produce BiF3. 5. The method of claim 4, wherein BiF3 used in producing said fluorinated compound comprises BiF3 produced from Bi2O3. 6. The method of claim 5, wherein said fluorinating agent comprises aqueous or anhydrous hydrofluoric acid, fluorine, or M′F, wherein M′ is alkali metal, alkaline earth metal, or a transition metal. 7. The method of claim 1, wherein Z is NR1. 8. The method of claim 7, wherein R1 is H. 9. The method of claim 8 further comprising the steps of producing a metal salt of said fluorinated compound, said steps comprising contacting said fluorinated compound with a carbonate compound of the formula M[CO3]m under conditions sufficient to produce said metal salt of said fluorinated compound, wherein M is an alkali metal, an alkaline earth metal, a transition metal, a lanthanide, or an actinide, and m is the oxidation state of M. 10. The method of claim 9, wherein said metal salt of said fluorinated compound comprises a lithium salt, sodium salt, potassium salt, cesium salt, magnesium salt, or a mixture thereof. 11. The method of claim 9, wherein said metal salt of said fluorinated compound is substantially halide free. 12. A method for producing a bis(fluorosulfonyl)imide of the formula: F—S(O)2—NR1—S(O)2—Fsaid method comprising contacting a bis(nonfluorohalosulfonyl)imide of the formula: X—S(O)2—NR1—S(O)2—Xwith BiF3 under conditions sufficient to produce said bis(fluorohalosulfonyl)imide,wherein each X is independently a halide provided at least one of X is a non-fluoro halide; andR1 is H, alkali metal, alkyl, or a nitrogen protecting group. 13. The method of claim 12, wherein X is chloro and R1 is H. 14. The method of claim 12, wherein said method produces BiX3, and wherein said method further comprises the step of contacting BiX3 with an oxygenating agent under conditions sufficient to produce Bi2O3, wherein said oxygenating agent comprises a metal carbonate, a hydroxide compound, water, oxygen, ozone, hydrogen peroxide, nitrous oxide, osmium tetraoxide, or a combination thereof. 15. The method of claim 14 further comprising the step of contacting Bi2O3 with a fluorinating agent under conditions sufficient to produce BiF3. 16. The method of claim 15, wherein BiF3 used in producing said bis(fluorohalosulfonyl)imide comprises BiF3 produced from Bi2O3. 17. The method of claim 12, wherein R1 is H, and said method further comprises contacting said bis(fluorosulfonyl)imide with a carbonate compound of the formula M[CO3]m under conditions sufficient to produce a metal salt of bis(fluorosulfonyl)imide of the formula: F—S(O)2—N(M)-S(O)2—Fwherein M is an alkali metal, an alkaline earth metal, a transition metal, a lanthanide, or an actinide; andm is the oxidation state of M. 18. The method of claim 17, wherein M comprises lithium, sodium, potassium, cesium, or magnesium. 19. The method of claim 17, wherein said metal salt of bis(fluorosulfonyl)imide is substantially halide free.
