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).

the development of a mild and fast photocatalytic trifluoromethylation of thiols. The combination of commercially available Ru(bpy)3Cl2, visible light and inexpensive CF3I gas proved to be an efficient method for the direct trifluoromethylation of thiols. The protocol is demonstrated on a wide range of aromatic, hetero-aromatic and aliphatic substrates in both batch and continuous microflow (32 examples
