発明の名称 (英語) Method for producing aromatic iodine compound
発明の概要(英語) 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 aromatic iodine compound, comprising the step of (a) 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 at least one selected from the group consisting of cyclic or acyclic ether compounds, being represented by the following General Formula (3): (see diagramm) (where: m is any integer in a range from 2 to 6; n is an integer not less than 1; R **1 and R **2 are identically or differently a hydrogen atom or a C 1-10 alkyl group; R **3 and R **4 are identically or differently a hydrogen atom or a C 1-10 alkyl group), wherein the iodizing agent is produced by a method comprising the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte.
[claim2]
2. The method of producing an aromatic iodine compound, according to claim 1, wherein: the cyclic ether compound contains a C 3-12 ring.
[claim3]
3. The method of producing an aromatic iodine compound, according to claim 1 or 2, wherein: the iodizing agent is an iodine cation.
[claim4]
4. The method of producing an aromatic iodine compound, according to any one of claims 1 through 3, further comprising the steps of: separating a solid reaction product from a reaction solution obtained in the step (a); and recrystallizing the reaction product thus separated from the reaction solution.
[claim5]
5. The method of producing an aromatic iodine compound, according to any one of claims 1 through 3, further comprising the step of isolating a reaction product by carrying out distillation process with respect to a reaction solution obtained in the step (a).
