Title:
METHOD FOR PRODUCING SULFONIUM SALT COMPOUND AND INTERMEDIATE THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/019983
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a sulfonium salt compound, with which a sulfonium salt compound having a variety of counter anions, particularly a sulfonium salt compound having weak acid-derived counter anions, can be efficiently produced, as well as providing a hydrogen carbonate sulfonium salt that is useful as a starting material in the method for producing a sulfonium salt compound. The present invention pertains to the following: a method for producing a sulfonium salt compound represented by general formula (2), which is characterized in that a hydrogen carbonate sulfonium salt represented by general formula (1) and an organic acid are reacted; and a hydrogen carbonate sulfonium salt represented by general formula (1'). (The symbols in the formulas are as defined in the specification.)
