The present invention provides a method of producing a tetracyanoborate-containing ionic compound in a milder condition more efficiently and less expensively than conventional methods, and a tetracyanoborate-containing ionic compound having a reduced content of impure components. An ionic compound of the present invention is represented by the following general formula (I), has a content of fluorine atom-containing impurities of 3 mol % or less per 100 mol % of the ionic compound, and a method for producing an ionic compound represented by the general formula (I) of the present invention comprises a step of reacting starting materials containing a cyanide and a boron compound. (In the formula, Ktdenotes an organic cation [Kt]or an inorganic cation [Ke]; and m denotes an integer of 1 to 3.)

A method of the present invention, for producing an iodizing agent, includes the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte. This realizes (i) a method of producing an iodine cation suitable for use as an iodizing agent that does not require a sophisticated separation operation after iodizing reaction is completed, and (ii) an electrolyte used in the method. Further, a method of the present invention, for producing an aromatic iodine compound, includes the step of causing an iodizing agent, and an aromatic compound whose nucleus has one or more substituent groups and two or more hydrogen atoms, to react with each other under the presence of a certain ether compound. This realizes such a method of producing an aromatic iodine compound that position selectivity in iodizing reaction of an aromatic compound is improved.
