METHOD FOR PRODUCING PERFLUOROALKYL GROUP-CONTAINING AROMATIC COMPOUND

Title:

METHOD FOR PRODUCING PERFLUOROALKYL GROUP-CONTAINING AROMATIC COMPOUND

Document Type and Number:

WIPO Patent Application WO/2023/074510

Kind Code:

A1

Abstract:

The present invention makes it possible to efficiently produce a perfluoroalkyl group-containing aromatic compound by reacting, in a solvent, a compound represented by general formula (3): R6Cu (3) [where R6 indicates a perfluoroalkyl group] and/or a complex, and a compound represented by general formula (2): (2) [where R1, R2, R3, R4, and R5 are the same as above, and X indicates a bromine atom or a chlorine atom]. The compound represented by general formula (3) and/or the complex thereof can be obtained by, for example, a step (I) for mixing, in a solvent, a compound represented by general formula (4): R6X2 (4) [where R6 is the same as above, and X2 indicates a bromine atom or an iodine atom], an inorganic material including copper, and a solvent so as to produce a compound represented by general formula (3) and/or a complex thereof.
