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).
