Abstract
KN(SO2F)2 is synthesized by adding HN(SO2Cl)2 dropwise to KF to form an intermediate product, and then allowing the intermediate product and KF to react with each other in an aqueous solvent.
Claims5
A method for producing a fluorine compound, in which a halogen element of a halogen compound represented by the following expression (1) is substituted with fluorine, to thereby synthesize a fluorine compound represented by the following expression (2), the method comprising:
- allowing the halogen compound and an alkali metal fluoride MF which is a fluoride of an alkali metal M to react with each other under solvent-free conditions to form an intermediate product, and then allowing the intermediate product and the alkali metal fluoride MF to react with each other in a polar solvent,
- HN(SO2X1)(SO2X2) (1)
- MN(SO2F)2 (2)
- where X1 and X2 each independently represent any element of Cl, Br, and I;
- and
- the alkali metal M represents any of Li, Na, K, Rb, and Cs.
A method for producing a fluorine compound, in which one halogen element of a halogen compound represented by the following expression (3) is substituted with fluorine, to thereby synthesize a fluorine compound represented by the following expression (4), the method comprising:
- allowing the halogen compound and an alkali metal fluoride MF which is a fluoride of an alkali metal M to react with each other under solvent-free conditions,
- HN(SO2X)2 (3)
- MN(SO2X)(SO2F) (4)
- where X represents any element of Cl, Br, and I;
- and
- the alkali metal M represents any of Li, Na, K, Rb, and Cs.
A method for producing a fluorine compound, in which a halogen element other than fluorine of a halogen compound represented by the following expression (4) is substituted with fluorine, to thereby synthesize a fluorine compound represented by the following expression (5), the method comprising:
- allowing the halogen compound and an alkali metal fluoride MF which is a fluoride of an alkali metal M to react with each other in a polar solvent,
- MN(SO2X)(SO2F) (4)
- MN(SO2F)2 (5)
- where X represents any element of Cl, Br, and I;
- and
- the alkali metal M represents any of Li, Na, K, Rb, and Cs.
