Abstract
A method of manufacturing a fluorine-containing aromatic compound represented by the following formula (2-1) or formula (2-2): [R is a hydrogen atom, an alkyl group having a carbon number of 1 to 12 which may have a substituent other than a fluorine atom, or a monovalent aromatic group which may have a substituent; Rf1 and Rf2 are a fluorine-containing alkyl group having a carbon number of 1 to 12 and Rf1 and Rf2 may be the same or different; and m is an integer of 1 or more, n is an integer of 0 or more and m+n is an integer of 1 or more and 5 or less].
Claims18
A method comprising:
- reacting a compound represented by the following formula (1) with a compound represented by the formula Rf1X1 in a halogen-containing solvent in the presence of a thiosulfate salt under light irradiation;
- and
- heating a resultant obtained in the reacting step,
- thereby obtaining a fluorine-containing aromatic compound represented by the following formula (2-1):
- [R is a hydrogen atom, an alkyl group having a carbon number of 2 to 12 which may have a substituent other than a fluorine atom, or a monovalent aromatic group which may have a substituent;
- Rf1 is a fluorine-containing alkyl group having a carbon number of 1 to 12 which may have a substituent;
- X1 represents an iodine atom or a bromine atom;
- and
- m is an integer of 1 or more, n is an integer of 0 or more and m+n is an integer of 1 or more and 5 or less].
