  Problem to be Solved It is intended to provide an industrially preferable fluoroalkylating agent and use thereof. Solution The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R 1 is a C1 to C8 fluoroalkyl group; R 2 and R 3 are each independently a C1 to C12 alkyl group or the like; Y 1 to Y 4 are each independently a hydrogen atom, a halogen atom, or the like; and X − is a monovalent anion. A compound of the general formula (3): R 4 —S—R 1 having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R 4 —S—Z wherein R 4 is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).

  要解决的问题 旨在提供一种工业上可取的氟烷基化剂及其使用方法。 解决方案 本发明提供了一种由通式（1）表示的氟烷基化剂，其中R 1 是C1到C8的氟烷基团；R 2 和R 3 分别独立地是C1到C12的烷基团或类似物；Y 1 到Y 4 分别独立地是氢原子、卤素原子或类似物；X − 是一价阴离子。 通式（3）的化合物：R 4 —S—R 1 ，其中引入了C1到C8的氟烷基团，可通过将通式（2）的化合物：R 4 —S—Z（其中R 4 是烃基团或类似物；Z是离去基团）与通式（1）的化合物反应而轻松获得。

A compound of the general formula (3): R4—S—R1 having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R4—S—Z wherein R4 is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).

  有待解决的问题 旨在提供一种工业上更理想的氟烷基化剂及其用途。 解决方案 本发明提供了一种由通式（1）表示的氟烷基化剂，其中 R1 是 C1 至 C8 氟烷基；R2 和 R3 各自独立地是 C1 至 C12 烷基或类似基团；Y1 至 Y4 各自独立地是氢原子、卤素原子或类似基团；X- 是单价阴离子。 通式（3）的化合物：将通式（2）的化合物与通式（1）的化合物反应，很容易得到具有引入的 C1 至 C8 氟烷基的 R4-S-R1 化合物：其中 R4 是烃基或类似物；Z 是离去基团。
