Title:
METHOD FOR PRODUCING TRIFLUOROMETHYL THIOALKYL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2016/076183
Kind Code:
A1
Abstract:
A method for producing a trifluoromethyl thioalkyl compound represented by general formula (1) (wherein R represents a C1-C10 alkyl group which may be substituted by R1, or the like; R1 represents a C1-C4 alkyl group or the like; and R2 represents a hydrogen atom, a halogen atom, a C1-C4 alkyl group or the like), which is characterized by adding thiophosgene at an addition temperature of 45°C or more for an addition time of 0.25 hour or more in the presence of a compound represented by general formula (2) (wherein R is as defined in general formula (1); and L represents a halogen atom, a C1-C4 alkylsulfonyloxy group or the like) and a fluorine compound.
