Paragraph 1525-1527, (2018/01/11)

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).
