Abstract
A method of producing a fluorine-containing compound is a method of producing a compound (30) having partial structure (3) by an insertion reaction of compound (20) into compound (10) that has partial structure (1), in the presence of an ionic catalyst formed from a specific monovalent anion and a counter cation. In the formulas, * represents a bonding site, and X1 and R1 to R4 each independently represents a hydrogen atom, a fluorine atom, a chlorine atom, or an organic group having a carbon number of 1 to 20 which may have a substituent.

A method of producing a compound having a partial structure represented by Formula (3), comprising:
- inserting a compound represented by Formula (20) into a compound having a partial structure represented by Formula (1) in the presence of an ionic catalyst formed from an anion and a counter cation, wherein
- the anion is a monovalent anion containing at least one type of element selected from the group consisting of iodine, nitrogen and sulfur, and
- the counter cation is a cation containing at least any one type of element among nitrogen or phosphorus, or is an alkali metal ion or a proton,
- wherein, * represents a bonding site and each of X1 and R1 to R4 independently represents a hydrogen atom, a fluorine atom, a chlorine atom, or an organic group having a carbon number of 1 to 20 which may have a substituent, and at least one of R1 to R4 is a fluorine atom or a chlorine atom.
A method of producing a copolymer, comprising:
- copolymerizing two or more types of compounds represented by Formula (20),
- wherein
- at least one type of the compound represented by Formula (20) is a compound represented by Formula (22), and the compound represented by Formula (22) is inserted into a compound having a partial structure represented by Formula (1), in the presence of an ionic catalyst;
- and
- inserting the compound represented by Formula (20) into a C—I bond by using a radical generator that is a compound different than the compound having a partial structure of Formula (1),
- wherein the ionic catalyst is formed from a monovalent anion containing at least one element selected from the group consisting of iodine, nitrogen and sulfur, and a counter cation, and the counter cation is a cation containing at least one element among nitrogen or phosphorus, or is an alkali metal ion or a proton,
- wherein * represents a bonding site, each of X1 and R1 to R4 independently represents a hydrogen atom, a fluorine atom, a chlorine atom, or an organic group having a carbon number of 1 to 20 which may have a substituent, each of X41 to X43 independently represents a hydrogen atom, a fluorine atom, a chlorine atom or —CX45X46X47, and each of X45 to X47 independently represents a hydrogen atom, a fluorine atom or a chlorine atom.
