In general formula (2-0-2), M+ represents an alkali metal  ion, or an ammonium ion which may have a substituent.  Examples of alkali metal ions include a sodium ion, a  lithium ion, and a potassium ion, and a sodium ion or a lithium  ion is preferable.  Examples of the ammonium ion which may have a sub› stituent include the same groups as those described above in  relation to formula (0-1).  Formula (0-0) is the same as defined above.  As the compound (2-0-1), commercially available com› pounds may be used, or the compounds may be synthesized  by a conventional method.  The method of producing the compound (2-0-1) is not  particularly limited. For example, referring to the method  described in Example 1 of Published Japanese Translation  No. Hei 11-502543 of the PCT International Publication,  silver fluoride (AgF), a compound represented by general  formula (2-0-11) shown below and a compound represented  by general formula (2-0-12) shown below can be reacted in an  organic solvent such as diglyme anhydride.  In general formula (2-0-12), as the halogen atom for  Xh,  a  bromine atom or a chlorine atom is preferable.  [Chemical Formula 82]  (2-0-11)  (2-0-12)  (2-0-1)  In the formulas, X 0 , Q 2  and pp are respectively the same as  defined for X 0 , Q $^{2 }$and pp in the aforementioned formula (2);  and  Xh  represents a halogen atom.  The compound represented by general formula (2-0-11)  can be produced, for example, by a method described in  Japanese Unexamined Patent Application, First Publication  No. 2006-348382 or U.S. Pat. No. 6,624,328 Bl.  The reaction temperature is preferably Oto 150°  C., and  more preferably Oto 100°  C. The reaction time depends on the  reactivity of the compounds (2-0-2) and (0-0), the reaction  temperature or the like. However, in general, the reaction time  is preferably 0.5 to 10 hours, and more preferably 1 to 5 hours.  In general, the amount of the compound (0-0) used in the  reaction is preferably 0.5 to 2 moles, per 1 mole of the com› pound (2-0-2).  After the reaction, the compound represented by general  formula (2-0) within the reaction mixture may be separated  and purified. The separation and purification can be con› ducted by a conventional method. For example, any one of  concentration, solvent extraction, distillation, crystallization,  recrystallization and chromatography can, be used alone, or  two or more of these methods may be used in combination.  (Anion Moiety (3))  A compound (3-0) having an anion moiety represented by  general formula (3) can be produced, for example, by reacting  a compound (3-0-1) represented by general formula (3-0-1)  shown below with a compound (0-0) represented by general  formula (0-0) shown below.  [Chemical Formula 83]  (3-0-1)  (0-0)  (3-0)  In general formula (3-0), X 10 , Q 3 , Y $^{10 }$and Y$^{11 }$are respec› tively the same as defined for X  10 , Q 3 , Y  $^{10 }$and Y $^{11 }$in general  formula (3).  Formula (0-0) is the same as defined above.  In general formula (3-0-1 ), M+ represents an alkali metal  ion, or an ammonium ion which may have a substituent.  Examples of alkali metal ions include a sodium ion, a  lithium ion and a potassium ion, and a sodium ion or a lithium  ion is preferable.  As an example of the ammonium ion which may have a  substituent, a group represented by the aforementioned gen› eral formula (0-1) can be given.  Formula (0-0) is the same as defined above.  The reaction between the compound (3-0-1) and the com› pound (0-0) can be effected by dissolving the compounds in a  solvent such as water, dichloromethane, acetonitrile, metha› nol, chloroform or methylene chloride, followed by stirring.  The reaction temperature is preferably Oto 150°  C., and  more preferably O to 100°  C.  The reaction time depends on the reactivity of the com› pounds (3-0-1) and (0-0), the reaction temperature or the like.
