Method for producing iodine-containing compound, and iodine-containing compound

A method for producing an iodine-containing compound, the method comprising reacting Compound (10) having a substructure represented by the following Formula (1) and a compound represented by the following Formula (3) in the presence of at least one selected from the group consisting of a compound represented by the following Formula (21) and a compound represented by the following Formula (22):

• wherein, in Formula (1), * represents a binding site bonded to an organic group;
• X represents a fluorine atom or a chlorine atom;
• X1 represents a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, or —CX5X6X7;
• and each of X5 to X′ independently represents a hydrogen atom, a fluorine atom, or a chlorine atom;
• wherein, in Formula (21), R21 represents a hydrogen atom, an iodine atom, or a substituted or unsubstituted organic group having from 1 to 20 carbon atoms;
• R22 represents a hydrogen atom, an iodine atom, a substituted or unsubstituted organic group having from 1 to 20 carbon atoms, or a boron-containing group, wherein a boron atom in the boron-containing group is bonded to the boron atom in Formula (21);
• R21 and R22 may be linked to form a ring structure;
• A1 represents a hydrogen atom, a chlorine atom, a bromine atom, or an iodine atom;
• and the boron atom in Formula (21) may be further coordinated with a ligand;
• wherein, in Formula (22), each of R23 and R24 independently represents a hydrogen atom, an iodine atom, or a substituted or unsubstituted organic group having from 1 to 20 carbon atoms, and R25 represents a hydrogen atom, an iodine atom, a substituted or unsubstituted organic group having from 1 to 20 carbon atoms, or a silicon-containing group, wherein a silicon atom in the silicon-containing group is bonded to the silicon atom in Formula (22), with the proviso that not all of R23 to R25 are hydrogen atoms;
• two or more of R23, R24, and R25 may be linked to form a ring structure;
• and A2 represents a hydrogen atom, a chlorine atom, a bromine atom, or an iodine atom;
• and
• wherein, in Formula (3), each of R1 to R4 independently represents a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, or a substituted or unsubstituted organic group having from 1 to 40 carbon atoms;
• and R1 and R4, or R2 and R3 may be linked to form a ring structure.
