-
Paragraph 0123; 0143, (2017/05/27)
A method of manufacturing a fluorine-containing aromatic compound represented by the following formula (2-1) or formula (2-2): R1 is a linear perfluoroalkyl group having a carbon number of 1 to 3; X2 to X5 are a halogen atom or a hydrogen atom; R2 to R5, L1 and L2 are a monovalent hydrocarbon group having a carbon number of 1 to 12, a monovalent aromatic hydrocarbon group, a monovalent hetero aromatic group, a halogen atom, or a hydrogen atom; one or more groups selected from R2 to R5 are a monovalent hydrocarbon group having a carbon number of 1 to 12, a monovalent aromatic hydrocarbon group, or a monovalent heteroaromatic group; and m is an integer of 0 or more, n is an integer of 1 or more, and m+n is an integer of 2 or more and 6 or less.

Commercially available anthraquinones were smoothly converted to either symmetrically or unsymmetrically substituted 9,10-bis(perfluoroalkyl)anthracene- 9,10-diols by way of bistrifluoromethylation or successive trifluoromethylation- nucleophilic perfluoroalkylation, respectively, and these diols can be easily aromatized to form bis(perfluoroalkyl)anthracene derivatives in good yields by treatment with a mixture of CBr4 and PPh3. Further cross-coupling reactions using halogen-containing anthracene derivatives realized a successful extension of the original π-conjugation systems.
