発明の名称 (英語) Method for producing iodizing agent and method for producing aromatic iodine compound
発明の概要(英語) 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.
特許請求の範囲(英語) [claim1]
1. A method of producing an iodizing agent, comprising the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte, wherein: the acid is at least one selected from the group consisting of: sulphonic acids and phosphoric acids, the sulphonic acids being represented by the following General Formula (1):

R **1SO 3H (1)

(where: R **1 is one selected from the group consisting of a hydroxyl group, a C 1-6 alkyl group, a phenyl group, and a naphthyl group; in the alkyl group, a hydrogen atom may be substituted with a fluorine atom; the phenyl group and the naphthyl group may have a substituent group); and the phosphoric acids being represented by the following General Formula (2): (see diagramm) (where: R **2 and R **3 are identically or differently a hydrogen atom, a C 1-10 alkyl group, or a phenyl group; and the phenyl group may have a substituent group).
[claim2]
2. The method of producing an iodizing agent, according to claim 1, wherein: the solution contains an organic solvent.
[claim3]
3. The method of producing an iodizing agent, according to claim 2, wherein: the organic solvent is at least one selected from the group consisting of aliphatic nitrile, alcohol, a chlorinated solvent, aliphatic amide, cyclic ether, and nitromethane.
[claim4]
4. A method of producing an iodizing agent, comprising the step of obtaining an iodine cation by electrolyzing an electrolyte, said electrolyte comprising an acid used as a supporting electrolyte; and
iodine molecules,
the acid having a concentration of not less than 0.01mol/L but not more than 19.0mol/L, wherein the acid is at least one selected from the group consisting of: sulphonic acids and phosphoric acids,
the sulphonic acids being represented by the following General Formula (1):

R **1SO 3H (1)

(where: R **1 is one selected from the group consisting of a hydroxyl group, a C 1-6 alkyl group, a phenyl group, and a naphthyl group; in the alkyl group, a hydrogen atom may be substituted with a fluorine atom; the phenyl group and the naphthyl group may have a substituent group); and
the phosphoric acids being represented by the following General Formula (2): (see diagramm) (where: R **2 and R3 are identically or differently a hydrogen atom, a C 1-10 alkyl group, or a phenyl group; and the phenyl group may have a substituent group).
[claim5]
5. The method according to claim 4, wherein a concentration of the iodine molecules is not less than 0.1 percent by mass but not more than 50 percent by mass.
