Patent ID: 7541492

Claim:
A method of manufacturing a compound of formula (1): wherein R f is selected from perfluoroalkyl groups having 1 to 4 carbon atoms, and Y + is selected from organic and inorganic cations, wherein the organic cation is selected from an imidazolium ion, a thiazolium ion, an oxazolium ion, an iso-oxazolium ion, a triazolium ion, a pyridinium ion, a pyridazinium ion, a pyrimidinium ion, a pyrazinium ion, an ammonium ion, a phosphonium ion, and a sulfonium ion, wherein each of the foregoing is substituted or unsubstituted, and the inorganic cation is selected from a proton, an ammonium ion, a hydroxonium ion, a lithium cation, a sodium cation, a potassium cation, a rubidium cation, a cesium cation, a silver cation, a copper cation, and a gold cation; the method comprising: preparing a compound of formula (2): wherein R f is selected from perfluoroalkyl groups having 1 to 4 carbon atoms, and is the same as the perfluoroalkyl group selected in said formula (1), and M + is selected from alkali metal cations and a silver cation; preparing a compound of formula (3): Y +− B (3) wherein Y + is selected from organic and inorganic cations, wherein the organic cation is selected from an imidazolium ion, a thiazolium ion, an oxazolium ion, an iso-oxazolium ion, a triazolium ion, a pyridinium ion, a pyridazinium ion, a pyrimidinium ion, a pyrazinium ion, an ammonium ion, a phosphonium ion, and a sulfonium ion, wherein each of the foregoing is substituted or unsubstituted, and the inorganic cation is selected from a proton, an ammonium ion, a hydroxonium ion, a lithium cation, a sodium cation, a potassium cation, a rubidium cation, a cesium cation, a silver cation, a copper cation, and a cold cation, and Y + in said formula (3) is the same as Y + in said formula (1), and − B is selected from organic and inorganic anions; and then reacting said compound of formula (2) with said compound of formula (3) to produce said compound of formula (1).
