Inventors include Shirai, Atsushi; Kuroki, Yoshichika Number; Kishikawa, Yosuke; and Manabe, Tomoyuki.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: Provided is a production method comprising a step A for reacting a compound represented by formula (2) [where R1, R2, and R3 are identical or different, R1 represents –COR, R2 and R3 represent a hydrogen atom or –COR, and R4 represents a C1-12 alkyl group or a C6-12 aryl group] with a fluorinating agent containing HF, an amine, and IF5 at not higher than 80°C from the start of the reaction to the end of the reaction. With this method, it is possible to synthesize a compound (N-fluoroalkylated hydrazine derivative) represented by formula (1) [where R1, R2, and R3 are the same as above, and each R is identical or different and represents a C6-12 aryloxy group or a C1-12 alkoxy group that may be substituted with one or more substituents].
