Title:
METHOD FOR PRODUCING FLUORINATED SULFONIUM ALKYLFLUOROPHOSPHATE
Document Type and Number:
WIPO Patent Application WO/2007/061024
Kind Code:
A1
Abstract:
Disclosed is a method for efficiently producing a fluorinated alkylfluorophosphoric acid salt of an aryl sulfonium at low cost without requiring an extremely excessive amount of acid. Specifically disclosed is a method for producing a sulfonium salt represented by the formula (3) below wherein an aryl compound Ar-H and a compound represented by the formula (1) below (wherein R1 and R2 respectively represent an optionally substituted hydrocarbon group or a heterocyclic group, or alternatively R1 and R2 are bonded together directly or via -O-, -S-, -SO-, -SO2-, -NH-, -NR’-, -CO-, -COO-, -CONH-, an alkylene having 1-3 carbon atoms or a phenylene and form an optionally substituted ring structure with R’ being a C1-5 alkyl or a C6-10 aryl) are reacted with each other in the presence of an acid represented by the formula (2) below (wherein Rf represents an alkyl in which 80% or more of hydrogen atoms are substituted by fluorine atoms, and a represents a number of 1-5) and a dehydrating agent.
