Title:
Fluoro alkylating agent
Document Type and Number:
Japanese Patent JP6046316
Kind Code:
B2
Abstract:
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).
