Title:
PROCESS FOR PRODUCING TRIARYLSULFONIUM SALT
Document Type and Number:
WIPO Patent Application WO/2005/037778
Kind Code:
A1
Abstract:
A process by which a triarylsulfonium salt in which only one aromatic ring differs from the others can be efficiently produced. The process, which is for producing a triarylsulfonium salt represented by the general formula [4]: (wherein R represents aryl optionally having a substituent different from R1; and A1 represents a strong-acid residue), is characterized by reacting a diaryl sulfoxide represented by the general formula [1]: with an aryl-Grignard reagent represented by the general formula [2]: RMgX (wherein X represents halogeno) in the presence of an activator having a high affinity for oxygen, the activator being used in an amount of 3 to 7.5 equivalents to the diaryl sulfoxide, and then reacting the reaction product with either a strong acid represented by the general formula [3]: HA1 or a salt of the acid.
