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 R1 is a C1 to C8 fluoroalkyl group; R2 and R3 are each independently a C1 to C12 alkyl group or the like; Y1 to Y4 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): 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。
